Assessment of risk in Patients With or Without Symptoms of Arrhythmia. Patients with symptomatic or asymptomatic idiopathic hypertrophic cardiomyopathy and postmyocardial infarction patient with left ventricular dysfunction using arrhythmia e.g.: ventricular ectopy, as method of risk assessment.
Assessment of efficacy of Antiarrhythmia Therapy. Patients with baseline high frequency, reproducible, sustained, symptomatic premature ventricular complexes supraventncular arrhythmia or ventricular tachycardia.
Assessment of Pacemaker Function. Evaluation of patients with paroxysmal symptoms, detection of myopotential inhibition, detection of pacemaker mediated tachycardia, evaluation of antitachycardia pacing device function, evaluation of rate-responsive physiological pacing function.
Detection of Myocardial Ischemia. Patients with chest pain suggestive of Prinzmetal’s angina.
