Abstract
Patients with ventricular tachycardia run a substantial risk of sudden death; therefore, therapy to prevent such arrhythmias is critical. However, noninvasive tests such as continuous electrocardiographic recordings, exercise testing, or both, often provide data insufficient for determining antiarrhythmic drug efficacy. For example, occurrences of arrhythmia may be separated widely in time, and many patients who are given drugs that seem to be effective at the time of hospital discharge die suddenly or are readmitted because of recurrent arrhythmias and/or syncope. Further, antiarrhythmic drugs are also arrhythmogenic and can result in sudden death although the arrhythmogenicity of the drug may not be apparent for weeks or months (Rinkenberger et al. 1982; Selzer and Wray 1964; Meltzer et al. 1978).
