Hypertrophic cardiomyopathy: sudden cardiac death in high risk patients and the role of arrhythmias

by Tarso Jorge, Paulo de

Abstract (Summary)
During 19 months of average follow-up period, we followed 26 patients with hypertrophic cardiomyopathy and high risk for sudden death, all treated by dual chamber implantable cardioverter-defibrillator. 4 patients had received appropriate ICD discharge, 4 patients with NSVT and 5 supraventricular arrhythmias. One death had occurred. Conclusions: we observed: supraventricular arrhythmias in 19,2%; NSVT in 15,4% and VT/VF in 15,4%. The clinical or demographic outcomes did not suggest any clinical or functional results after ICD implantation; syncope may occur after ICD implantation and no arrhythmias recordered by intracardiac electrograms and left-ventricular-wall thickness greater than 30 mm is associated with early ICD shocks (p=0,003).
