    The New Technology Used In The Cardiac Monitor

    The standard cardiac monitor that has been available in the healthcare industry for years is designed to monitor the heart’s activity. This includes the pulse rate as well as the rhythm. For those with cardiac disease as well as those who have recently had a heart attack or stroke, the monitor is used to let doctors find out what is going on. It can be used to catch problems early on and ensure that a person is getting the level of healthcare they need.

    Traditionally, the cardiac monitor was a large machine that was found in hospitals as well as some doctor offices. When a person needed to be monitored, they were hooked up to the machine with a variety of leads. In many instances, the person would have to stay overnight at the hospital for monitoring. Between the equipment, the doctor visits, and the overnight, the bill would be very expensive.

    Even those with health insurance would feel the financial burden because of the out of pocket expenses. People would still be responsible for some of the costs – and this led those in the technology industries to look at making improvements.

    Today, it’s possible to find mobile cardiac monitors that allow a person to have their cardiac activity monitored from the comfort of their own home. The units are much smaller and there are less leads connected to the person. Much of the information can be transported via a wireless connection so that doctors can view the activity in real-time.

    Depending upon the technology used in the cardiac monitor, doctors will be able to get alerts when the activity is in need of immediate monitoring. This can ensure that patients are getting the level of care they need. If something on the monitor is cause for concern, the doctor can find out about it and request that the patient go right to the hospital in order to meet with the doctor.

    As new technology comes out with more mobile devices, smaller computer chips, and other forms of telemetry, patients around the country are able to see improvements in the way they can have their heart monitored. There are no more overnight stays at the hospital simply for having the heart monitored. This allows patients to lead a normal life – and even go to work while having their heart monitored.

    Doctors and patients both find that the cardiac monitor has changed for the better, ensuring that money is saved and results are seen in real-time. No one has to worry about not being able to share results with the doctor. They can be downloaded from the device or sent electronically, depending upon the model.

    New technology has made improvements all across the healthcare industry. The next time someone needs their heart monitored, it is of the essence to look into a mobile cardiac monitor simply because it is more cost effective and more productive in terms of the results that it can provide.

    The Recommendations For The Use Of Ambulatory ECG For Assessing Symptoms Of Arrhythmia

    The American College of Cardiology (ACC) and the American Heart Association (AHA), in collaboration with the North American Society for Pacing and Electrophysiology, have developed guidelines for the use of ambulatory electrocardiography (ECG). The guidelines include recommendations for the evaluation of symptoms of cardiac arrhythmias; for risk assessment in patients who have sustained a myocardial infarction, have congestive heart failure (CHF) or have hypertrophic cardiomyopathy; for the evaluation of antiarrhythmic therapy, or pacemaker or implantable cardioverter-defibrillator function; and for the evaluation of possible myocardial ischemia. There is also a section on the use of ambulatory ECG for the evaluation of children with cardiac symptoms.

    The eight-page executive summary of the guidelines appears in the August 24, 1999 issue of Circulation. The guidelines are published in their entirety in the September 1999 issue of the Journal of the American College of Cardiology. The complete guidelines are also available on the above-mentioned ACC and AHA Web sites. A single reprint of the executive summary (reprint no. 71-0171) can be obtained by calling 800-242-8721 or writing the American Heart Association, Public Information, 7272 Greenville Ave., Dallas, TX 75231-4596. Reprints of the complete guidelines (reprint no. 71-0172) cost $5 and can be obtained by calling 800-253-4636 or writing the American College of Cardiology, Resource Center, 9111 Old Georgetown Rd., Bethesda, MD 20814-1699.

    The recommendations are classified according to the system used by the ACC and AHA. The classification system is as follows:

    Class I—Conditions for which there is evidence and/or general agreement that a given procedure or treatment is useful and effective.

    Class II—Conditions for which there is conflicting evidence and/or a divergence of opinion about the usefulness/efficacy of a procedure or treatment. Class IIa—The weight of evidence/opinion is in favor of usefulness/efficacy. Class IIb—The usefulness/efficacy is less well established by evidence/opinion.

    Class III—Conditions for which there is evidence and/or general agreement that the procedure/treatment is not useful/effective, and in some cases may be harmful.

    The recommendations for the use of ambulatory ECG for assessing symptoms of arrhythmia, the risk of arrhythmias, the efficacy of antiarrhythmic therapy, the function of pacemakers and implantable cardioverter defibrillators and monitoring myocardial ischemia.

    Analysis Of Symptoms Of Cardiac Arrhythmias

    The guidelines state that one of the primary and most widely accepted uses of ambulatory ECG is determining the association of a patient’s transient symptoms to cardiac arrhythmias. The crucial information needed is the recording of an ECG during the precise time that the symptom is occurring. The recommendations note that the yield of ambulatory ECG monitoring in syncope is relatively low. However, because of the severity of symptoms, such testing is usually warranted. The yield of ambulatory monitoring that captures an episode of palpitation is higher than the yield in patients with syncope. Ambulatory ECG monitoring may also be indicated in the evaluation of other symptoms that may be related to cardiac abnormalities, such as intermittent shortness of breath, unexplained chest pain, episodic fatigue or diaphoresis.

    The indications for ambulatory ECG monitoring for symptoms of arrhythmia are as follows:

    Class I—(1) Patients with unexplained syncope, near syncope or episodic dizziness without obvious cause. (2) Patients with unexplained recurrent palpitation.

    Class IIb—(1) Patients with episodic shortness of breath, chest pain or fatigue that is not otherwise explained. (2) Patients with neurologic events when transient atrial fibrillation or flutter is suspected. (3) Patients with symptoms such as syncope, near syncope, episodic dizziness or palpitation in whom a probable cause other than an arrhythmia has been identified but in whom symptoms persist despite treatment of this other cause.

    Class III—(1) Patients with symptoms such as syncope, near syncope, episodic dizziness or palpitation in whom other causes have been identified by history, physical examination or laboratory tests. (2) Patients with cerebrovascular accidents, without other evidence of arrhythmia.

    Intermittent Short ECG Recorder Is More Effective In Detection Of Arrhythmias

    Many patients report symptoms of palpitations or dizziness/presyncope. These patients are often referred for 24-hour Holter ECG, although the sensitivity for detecting relevant arrhythmias is comparatively low. Intermittent short ECG recorder over a longer time period might be a convenient and more sensitive alternative. The objective of this study is to compare the efficacy of 24-hour Holter ECG with intermittent short ECG recorder over four weeks to detect relevant arrhythmias in patients with palpitations or dizziness/presyncope.

    Intermittent short ECG recorder during four weeks is more effective in detecting AF and PSVT in patients with ambiguous symptoms arousing suspicions of arrhythmia than 24-hour Holter ECG.

    Patient-operated intermittent ECG recorders could potentially improve the diagnosis of transitory ECG changes in such patients and may give results comparable to standard external loop event recorders [5,6]. The advantage of such devices compared to standard external loop event recorders is that they are reasonably priced and easy to use, especially as no external electrodes are necessary.

    Even when using (handheld or standard external loop) event recorders, episodes of an arrhythmia may be missed as the correlation between symptoms and relevant arrhythmias is often not very strong. In atrial fibrillation (AF), for example, it is known that only one in 10 paroxysms is symptomatic [7]. The European Heart Rhythm Association stated in a 2011 position paper on palpitations that it is especially important to exclude AF as the underlying cause of symptoms in patients with palpitations of unknown origin, as AF is associated with an increased risk of thrombo-embolism [8-10]. Recent studies show that intermittent ECG recorder with both regular and symptomatic registrations detects more episodes of silent AF in patients with known paroxysmal atrial fibrillation compared with 24-hour Holter ECG [11] and improves the detection of previously unknown asymptomatic paroxysmal atrial fibrillation (AF) in post-stroke patients.

    The objective of this study is to compare the efficacy of short intermittent ECG registrations with 24-hour Holter ECG, in detecting relevant arrhythmias in patients reporting symptoms of palpitations and dizziness/presyncope.

    Ambulatory ECG Monitoring Can Identify Asymptomatic Patients At Risk Of Arrhythmias

    According to the guidelines, ambulatory ECG monitoring is increasingly used to identify asymptomatic patients at risk of arrhythmias, such as after a myocardial infarction, in congestive heart failure and in hypertrophic cardiomyopathy. With myocardial infarction, 24-hour ECG monitoring is frequently performed before the patient is discharged from the hospital. Frequent premature ventricular contractions and high-grade ventricular ectopy are associated with a higher mortality rate among survivors of myocardial infarction.

    Patients with CHF often have complex ventricular ectopy and a high mortality rate. Several studies have found that ventricular arrhythmias are sensitive but not specific markers of death and sudden death. There are divergent results with respect to the association between heart rate variability and arrhythmic events. According to the guidelines, there is not sufficient evidence to support the routine use of ambulatory ECG or heart rate variability monitoring in patients with CHF or dilated cardiomyopathy.

    Although ambulatory ECG monitoring may provide prognostic information in patients with hypertrophic cardiomyopathy, the guidelines state that treatment of ventricular arrhythmias has not been shown consistently to increase life expectancy. Therefore, the role of ambulatory ECG in the day-to-day treatment of these patients remains unclear.

    The guidelines state that three groups may benefit from ambulatory ECG or heart rate variability monitoring: patients with idiopathic hypertrophic cardiomyopathy, patients with CHF and patients who have had a myocardial infarction and have a reduced ejection fraction. However, the tests currently cannot be recommended for routine use in any other population.

    The indications for ambulatory ECG monitoring to detect arrhythmias and to assess the risk of cardiac events in patients without symptoms are as follows:

    Class I—None.

    Class IIb—(1) Postmyocardial infarction patients with left ventricular dysfunction (ejection fraction of 40 percent or less). (2) Patients with CHF. (3) Patients with idiopathic hypertrophic cardiomyopathy.

    Class III—(1) Patients who have sustained a myocardial contusion. (2) Systemic hypertensive patients with left ventricular hypertrophy. (3) Postmyocardial infarction patients with normal left ventricular function. (4) Preoperative arrhythmia evaluation of patients for non-cardiac surgery. (5) Patients with sleep apnea. (6) Patients with valvular heart disease.

    Ambulatory ECG Monitoring Used On Implanted Cardiac Devices

    According to the recommendations, ambulatory ECG monitoring is useful in assessing the function of cardiac pacemakers and implantable cardioverter defibrillators and for guiding appropriate programming of such devices. Monitoring is also useful for correlating intermittent symptoms with the device activity and for establishing the appropriateness of cardioverter-defibrillator shock therapy during follow-up.

    The indications for ambulatory ECG monitoring to assess pacemaker and implantable cardioverter-defibrillator function are as follows:

    Class I¡ª(1) Evaluation of frequent symptoms of palpitation, syncope or near syncope to assess device function to exclude myopotential inhibition and pacemaker-mediated tachycardia and to assist in the programming of enhanced features such as rate responsivity and automatic mode switching. (2) Evaluation of suspected component failure or malfunction when device interrogation is not definitive in establishing a diagnosis. (3) To assess the response to adjunctive pharmacologic therapy in patients receiving frequent cardioverter-defibrillator therapy.

    Class IIb¡ª(1) Evaluation of immediate postoperative function after implantation of the device as an alternative or adjunct to continuous telemetric monitoring. (2) Evaluation of the rate of supraventricular arrhythmias in patients with implanted defibrillators.

    Class III¡ªAssessment of device malfunction when device interrogation, ECG or other available data (e.g., chest radiograph) are sufficient to establish an underlying cause/diagnosis. (2) Routine follow-up in asymptomatic patients.
