Are ventricular tachycardia occurrences randomly distributed over time in individual patients with implantable cardioverter-defibrillators?
Ventricular tachyarrhythmias exhibit temporal clustering rather than random distribution, suggesting a potential role for preemptive antiarrhythmic therapy.
Wood et al. (1995) studied this question.
