Heart failure is the most common discharge diagnosis in the United States, with a prognosis worse than many cancers.1 Patients with heart failure die for two reasons: advanced circulatory insufficiency or sudden death.2 We know that continuous online monitoring of cardiac rhythm from patients with advanced heart failure is inevitably abnormal and often shows long runs of irregular and/or polymo...
A 55 year old male presented with recurrent implantable cardioverter defibrillator (ICD) shocks due to polymorphic ventricular tachycardia (PMVT). He had undergone prior catheter ablation for VT three years ago. During the prior attempt he underwent voltage guided substrate ablation. With programmed ventricular extrastimulation (PVES), PMVT was repeatedly induced requiring DC shock. Intravenous...
Polymorphic ventricular tachycardia and ventricular fibrillation (VF) carry important prognostic implications, especially in the post myocardial infarction period. However, artifact on the electrocardiographic tracing can mimic VF particularly on routinely recorded rhythm strips in hospitals. Such misinterpretation can lead to expensive (and potentially risky) diagnostic and therapeutic steps. ...
Objective: A naturally-occurring mutation in cardiac calsequestrin (CASQ2) at amino acid 307 was discovered in a highly inbred family and hypothesized to cause Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT). The goal of this study was to establish a causal link between CASQ2 and the CPVT phenotype using an in vivo model. Methods and results: Cardiac-specific expression of the CASQ...
propafenone hci (p), is a relatively new class ic antiarrhythmic agent. it has been reported to be superior to conventional antiarrhythmics in the control of supraventricular, ventricular and wpw associated tachyarrhythmias. it has been also shown to be well tolerated. in our study protocol, which extends over 2~ years period , we used (p) in 87 patients for management of various types of cardi...
Electrophysiological testing was performed in 100 consecutive patients with spontaneous asymptomatic nonsustained ventricular tachycardia, chronic coronary artery disease, and ejection fraction of less than 40%. Fifty-seven patients without inducible sustained ventricular arrhythmias were discharged on no antiarrhythmic therapy. Sustained monomorphic ventricular tachycardia was induced in 37 pa...
OBJECTIVE To study the outcome of patients with arrhythmogenic right ventricular dysplasia treated with an implantable cardioverter-defibrillator (ICD) for ventricular tachyarrhythmias complicated by haemodynamic collapse. DESIGN Observational study. SETTING University hospital. PATIENTS Nine consecutive patients (eight male, one female; mean (SD) age, 36 (18) years) with arrhythmogenic r...
