The reproducibility of electrophysiologic testing on successive days was assessed in the
absence of antiarrhythmic drug treatment. Forty-two patients, 17 with compromising …

Sixty-four patients with symptomatic ventricular tachycardia or ventricular fibrillation
underwent right ventricular apical programmed stimulation and had no inducible ventricular …

The provocation or worsening of arrhythmias by antiarrhythmic regimens was evaluated in

Long-term continuous electrocardiographs recordings (Holter recordings) and
electrophysiologic testing are useful for selecting patients for antiarrhythmic drug trials and …

From a population of 260 patients with malignant ventricular arrhythmia (ventricular
fibrillation or ventricular tachycardia with syncope) we identified 52 (20%) who had …

Selection of an antiarrhythmic drug program by non-invasive means for patients with
malignant ventricular arrhythmia has not been demonstrated to be the decisive factor in …

The relationship between arrhythmia density observed during ambulatory monitoring, left
ventricular ejection fraction (EF), and response to antiarrhythmic drug therapy was evaluated …

BACKGROUND Surviving myocardial cells near the infarct border zone form the
arrhythmogenic substrate for sustained ventricular tachycardia (VT) in humans. Infarct …

Ventricular arrhythmias are common and cause serious problems, ranging from symptom
