Filter by:To acquire a better understanding of the spontaneous clinical behavior of paroxysmal tachycardia by studying epidemiologic features of symptomatic tachycardia patients.
To determine if the dietary N-3 class of polyunsaturated fatty acids (PUFAs) provided in the diet largely from marine fish oils would prevent fatal ventricular tachycardia (VT) or ventricular fibrillation (VF).
To determine the antiarrhythmic effects of dietary N-3 fatty acids in patients with implanted defibrillators.
To evaluate if use of an implantable cardiac defibrillator (ICD) results in reduction in total mortality, when compared with conventional pharmacological therapy, in patients resuscitated from sudden cardiac death who are otherwise at very high risk of mortality from arrhythmic causes.
To determine whether electrophysiologic study (EPS) or Holter monitoring (HM) was the better method for selecting effective long-term antiarrhythmic drug therapy in patients with sustained ventricular tachycardia, ventricular fibrillation, or an episode of aborted sudden death.
To determine the value of electrophysiologic (EP)-guided antiarrhythmic therapy in coronary heart disease patients at increased risk for sudden death. The study included a controlled clinical trial and a registry.
