Background Patients with reduced left ventricular function after myocardial infarction are at
risk for life-threatening ventricular arrhythmias. This randomized trial was designed to …

Background Unsustained ventricular tachycardia in patients with previous myocardial infarction
and left ventricular dysfunction is associated with a two-year mortality rate of about 30 …

Background— In 1994, an International Task Force proposed criteria for the clinical diagnosis
of arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) that facilitated …

Background This trial was designed to determine whether cardiac-resynchronization therapy
(CRT) with biventricular pacing would reduce the risk of death or heart-failure events in …

Background Patients with nonischemic dilated cardiomyopathy are at substantial risk for
sudden death from cardiac causes. However, the value of prophylactic implantation of an …

Background The implantable cardioverter–defibrillator (ICD) is highly effective in reducing
mortality among patients at risk for fatal arrhythmias, but inappropriate ICD activations are …

Background Hypertrophic cardiomyopathy is a genetic disease associated with a risk of
ventricular tachyarrhythmias and sudden death, especially in young patients. Methods We …

Objectives : This study sought to identify the incidence and outcome related to inappropriate
implantable cardioverter-defibrillator (ICD) shocks, that is, those for nonventricular …

Background— This study aimed to determine whether QRS morphology identifies patients
who benefit from cardiac resynchronization therapy with a defibrillator (CRT-D) and whether it …

ContextRecently, the implantable cardioverter-defibrillator (ICD) has been promoted for
prevention of sudden death in hypertrophic cardiomyopathy (HCM). However, the effectiveness …
