    Holter ECG

    We have seen doctors using Stethoscope to examine patients. By using the stethoscope doctors listen to the internal sounds of the body, especially heart beating, lungs,intestines etc. During each heart beat, small electrical signals are generated along with the sound. These electrical activity of human heart is measured and monitored by using electrocardiogram (ECG). Electrodes are attached to the outer surface of the skin, which detects the signals. These signals are amplified and recorded on ECG paper by ECG machine.

    For diagnosis and monitoring of heart and heart diseases different types of ECG is used.

    Resting ECG

    A Resting Electrocardiogram (ECG) is used to analyse how the heart performs when the person is at rest. This test aids the doctor in evaluating the condition of the heart. It is also used to monitor patients who have undergone an angiogram, angioplasty, cardiac surgery or change in dosage of heart medication. The Resting ECG helps to detect a wide range of heart conditions and takes approximately 15-20 mins.

    Stress Test (Exercise ECG)

    The ECG obtained when the heart is working harder due to exercise or medication induced stress is termed exercise ECG, or stress test. This test is useful in detecting problems that may not be detected in a resting ECG. It also shows any abnormal flows of blood to muscle tissue. The stress test is done by trained personnel under a controlled environment.

    Stress test is used as a screening tool for people with coronary artery disease. This test can help predicting future heart attacks in people with multiple risk factors even if the person doesn’t have any heart disease.

    Holter ECG

    A Holter monitor is a portable device for continuously monitoring the electrical activity of the cardiovascular system for at least 24 hours. The Holter monitor is named after its inventor, Norman J. Holter. The increased recording period can be useful for detecting arrhythmia, the condition in which the heart can beat too fast, too slow, or with an irregular rhythm. The electrodes are placed over bones to minimize the readings obtained from muscular activity. Most Holter monitors employ between three and eight electrodes. These electrodes are connected to a small piece of equipment that is attached to the patient’s belt or hung around the neck. This recorder keeps a log of the electrical activity of the heart.

    Holter monitoring is used mainly after a heart attack,to diagnose heart rhythm problems and when starting a new heart medicine.

    Monitoring in ICU

    Using the continuous measurement of the heart’s electrical activity, the ICU staff can monitor if the heart is beating abnormally fast or slow and if the heart is following a normal or abnormal rhythm. The ECG is one of the most common monitoring devices used in the hospital. The variations in the heart rate or rhythm may be the first sign of an adverse or abnormal development, and they help to alert the doctor or nurse. Thus it is a reliable and frequently used method of patient-monitoring in the ICUs.

    Monitoring in Operation Theatres

    Up to 86% of patients experience cardiac arrhythmia during anaesthesia and surgery. Many such occurrences are of clinical significance and therefore their detection is very important. The ECG monitor should always be connected to the patient before administration of anaesthesia. This will aid the anaesthetist in detecting changes in the heart rhythms (if any) during anaesthesia..

    Portable ECG Recorder On Sale 

    Electrocardiogram monitors or ECG machines are devices which are basically used to detect heart diseases and monitor the electrical activity of the heart. It is highly beneficial in detecting cardiovascular diseases. These machines can detect damaged and diseased tissues, rate of heartbeat, structural abnormalities, surgical repairs and so forth. It can also detect the effects of certain drugs on the heart.

    As it is one of the safest and least invasive methods, it is used by millions of cardiologists all over the world to detect the problems and functions of the heart. The electrocardiogram is depicted in the form of electrical waves which are represented on paper. These waves vary according to the health condition of the heart.

    Different Parts of an Electrocardiogram Machine:

    This machine is not a single instrument but a group of devices which work together to record and detect the activity of the heart. It reads the impulses of the heart and translates it into a graph style diagram. It is then printed on paper strips.

    Electrodes: The machine includes a set of lead wires which include small metal discs at the end of the wire. These discs are soft and adhesive which are attached to the arms, legs and chest to monitor and record the rhythm of the heart. These electrodes are attached to the main unit of the machine. Majority of the electrocardiogram machine utilize 12 electrodes to monitor the functions of the heart.

    Amplifier: The amplifiers are devices which receive the electrical signal from the electrodes and convert the information. These amplifiers include various sections and functions. The signal received from the human body is relatively weak and it must be amplified so that it can be stabilized. The amplifier includes a buffer amplifier and a preamplifier which help to convert the information so that it can be read by the output device. However, the amplifier is separated from the main unit of the machine so as to safe guard the patients from electrical shocks.

    Output Devices: The ECG machine includes various output devices such as a recorder which records and prints the ECG signal, computers, magnetic tapes, oscilloscopes and so forth. The final output of information includes a paper strip which indicates electrical signals. It can be used to diagnose heart disease and detect recent cardiac arrest and other abnormalities.

    Another common type of device includes the holter monitors which are basically portable machines that are used to diagnose abnormal heart rhythms. It is quite similar to the conventional types of devices but it includes various additional features. It includes a portable ECG recorder and three electrodes. The electrical output detected from the heart can be stored in this device so that it can be evaluated by the doctor.

    There are various types of electrocardiogram devices which can be bought from online stores easily. The two most common types of machines include the 3-lead and 5-lead machines which are portable. The 12-lead machine is another type of electrocardiogram machine which can be used to detect the activities of the heart from twelve different angles.

    Test Of ECG Rhythms

    ECG is an abbreviation for an electrocardiograph. An ECG records the heart’s electrical activity as a graph or a series of wavy lines on a moving strip of paper. It provides information on a patient’s heart rate and rhythm and blood flow. It is used to diagnose medical problems such as a heart attack or irregular heartbeats.

    Heart rhythm problems or arrhythmias can be diagnosed using a variety of methods. The method depends upon the specific heart rhythm problem suspected by a physician. An electro physiology is done when the arrhythmia is identified as a fast heart rhythm problem called tachyarrhythmia.

    There are different types of ECG tests that help record the heart’s rhythm of patients. The exercise ECG or stress test is a graphical recording of the heart’s rhythm during exertion. The exertion is created using a treadmill machine. This test helps to evaluate whether exercise can create an arrhythmia or make it worse. It also helps diagnose a condition involving insufficient flow of blood to the heart called ischemia.

    An ECG rhythm is recorded for long and short periods of time. A Holter monitor is a 24-72 hour ECG. It is a device that measures and records the heart rhythm over 1-3 days. This test may be done when an ECG does not clearly show the arrhythmia, though it is suspected to be the underlying cause of the symptoms. In a ECG Rhythm test, patches with wires are placed on the patient’s chest. The wires are connected to a portable monitor that can be attached to a purse or belt.

    An external loop recorder is a device that monitors the heart rhythm and rate for up to one month. During this test, the patient wears a device on the wrist or around the waist. When symptoms are experienced, the patient presses a button on the device to make a recording of the heart activity that just occurred.

    An insertable loop recorder is a device that continuously monitors the heart rhythm for up to 14 months. This small device is placed under the skin during a twenty-minute procedure using a local anesthetic. When a symptom is experienced, the patient places a hand-held activator over the recorder. Later, a physician analyzes the stored information. ECG rhythms help diagnose problems that can be cured when detected. It is just one of many applications of an ECG that has a life saving impact.

    Miniature portable ECG monitors

    There are a variety of handheld ECG monitor types, a.k.a. portable EKG machines, available in the today’s marketplace. It is especially encouraging and empowering to the patient that many of them are designed for use by patients and their caregivers at home.

    We will present here three great reasons why using a hand held ECG monitor at home is an idea worth pursuing. They are – miniaturization of ECG monitors has made these devices highly portable and convenient for use just about anywhere, the ECG interpretation information is becoming inexpensively, and widely available, and, finally, the cost.

    Using ECG monitors at home is becoming easier due to the extremely small size of the device. The wires (electrodes) can be organized in a simple plastic belt, and the monitor device itself can be as small as the credit card, and as thin as 0.4 in. This makes a modern portable ECG easy to wear by anyone, and for extended periods of time. Also, due to a smartly organized all-in-one electrode wire design, the shorts are highly unlikely. Some manufacturers even introduced wireless connection between the electrodes and the main unit, reducing the amount of wires and increasing the comfort even further. Both the electrode part of the unit would have a wireless transceiver built in, and the main unit would feature a wireless transceiver as well. Then, the main unit can optionally be worn on the patient’s body, or it could even be removed and kept at a small distance.

    ECG test interpretation is becoming accessible

    There are several books and how-to guides available for purchase and with them, even a lay person can become an expert in reading ECG recorder printouts. That is not to say that an expert doctors opinion is still the best way to go, but, by being able to read your own ECG signals, you will be better prepared to know when to go ahead and call a doctor or show up in the emergency room. Good education just adds an additional layer of safety, if it is not overdone. Although many doctors would disagree by saying “a little knowledge is a dangerous thing”, as long as you are conscious enough of the limitations of your knowledge, and do not rely on your own opinion entirely, and are perfectly willing to call a doctor when you see or feel a problem, you should be okay. Some doctors will even be able to suggest treatment changes such as medication changes by checking the data from the ECG remotely.

    Finally, handheld ECG equipment cost vs. cost of hospital stay

    All but the most recent wireless portable ECG units have experienced the transition into the mainstream electronics, and consequently, the prices of handheld ECG monitors have begun to fall into the highly affordable territory. There are several US and Chinese manufacturers that are all designing and manufacturing highly reliable devices, at a good price. The price of handheld ECG monitors is especially appealing when compared to the cost of an overnight stay at the hospital to perform ECG measurements, or even compared to a single specialist visit.

    How to do with the problems of ECG or EKG Recorder

    Electrocardiogram, widely known as ECG or EKG (Electrocardiogram in German/Dutch), is a common cardiac test which helps in detecting various cardiac abnormalities. This test is mainly done to test the electrical activity of the heart.

    The electrical activity of the heart is represented by an electrocardiograph reproduced by a tool or software called ECG Simulator. There are different kinds of simulators with different number of leads (10 or 12) and types of patient cables. The compatibility of the leads and patient cables should always be checked with the diagnostic equipment.

    A normal ECG records problems with the heart’s rhythm and the conduction of the heart beat. It helps discover different problems and also a patient’s response to the treatment.
    ECG can be done when there are symptoms of chest pain (angina), difficulty in breathing, fainting and palpitations. It can show evident disease in coronary arteries and the effect of medications on it. It can also reveal a previous heart attack or the cause of slow or fast heart beat. It can also help to demonstrate thickening of a heart muscle and to know the mineral content in the blood. However, ECG is not an exhaustive test and it may not trace an underlying significant heart disease, hence other tests are needed. One can also read about it or watch the top medical videos online to gain more information about it.

    Electrocardiogram ECG is a harmless test with no danger at all. This test is usually taken when patient is completely at rest. But sometimes the disease or thickening of coronary arteries is not detected and hence an exercise test is performed. The patient may get chest pain which would be resolved after the exercise is stopped. Exercise test should be done in supervision of the doctors and the ECG technicians. The test can be discontinued in case of major chest pain, drop in BP, changes on ECG or achievement of target heart rate.

    An ECG is performed with 10 or 12 self adhesive electrodes (or cables) attached to arms, legs and chest on clean and shaved skin. The test is harmless and it does not even take a minute once the leads are in position. The doctor then gives suggestions after reviewing the paper print out of ECG.

    As the ECG test is not the ultimate and it has to be supplemented with other tests, the options are radioisotope perfusion scan – which uses low dosage radioactive dye to show the areas having good and bad supply of blood or angiography – which is the X-ray examination, for determining illness and its cause..

    Heart Diseases are the leading cause of death in western countries, when compared to other diseases. It is now gradually replacing infectious diseases in developing countries as the main cause of population getting hospitalized for treatment. Many of the uneducated sections of the populations, who cannot afford treatment in time, succumb to this deadly disease. Around 63.4 % of the heart disease deaths are classified under sudden death category. These are patients who die before reaching the nearest hospital.

    Numerous studies demonstrate that all patients with diagnosed heart disease and people with high risk of developing heart disease would benefit by early monitoring for rapid detection of abnormal heart events or for diagnosis of heart disease with heart muscle abnormalities which in many cases can be easily done using electrocardiographs (ECG/EKGs).Getting a ECG or EKG done at hospital or clinic can be difficult for many patients. Either there may be a long line in the emergency room, or the tests could be expensive. So what is the other option for these patients? Single Lead ECG (EKG) recorders are used in monitoring of different types of abnormal heart rhythms in patients suffering from heart diseases. These are useful medical devices in characterizing arrhythmias, monitoring anti-arrhythmic medicines and drug toxicity evaluation.They could also be used as a research based tool instead of standard 12 lead based ECG(EKG) recorders.

    Current ECG recording machines are expensive, are heavy devices with complex operational procedures and can be difficult to use especially at home care setting. The current generation of home based personal ecg machines can be used with ease. They can help in early detection of any abnormal heart rhythms and thereby, prevent damage caused by heart disease. The health care professionals including doctors and nurses can quickly diagnose any damage to the heart muscles and plan for rapid treatment. Personal EKG machines are now commonly used in many homes for early detection of heart disease. The small portable ECG machines can also be used at health care centers including sporting centers and fitness centers. These help to detect any heart disease in patients who are using exercising equipments.
