IMPORTANCE: Over 10 000 people with Chagas disease experience sudden cardiac death (SCD) annually, mostly caused by ventricular fibrillation. Amiodarone hydrochloride and the implantable cardioverter-defibrillator (ICD) have been empirically used to prevent SCD in patients with chronic Chagas cardiomyopa...
INTRODUÇÃO: A síndrome arritmogênica do prolapso valvar mitral (PVM) é uma condição associada a eventos arrítmicos ventriculares e morte súbita cardíaca (MSC). O acompanhamento por telemetria do cardioversor-desfibrilador implantável (CDI) pode aprimorar a compreensão dessa síndrome por ser ...
INTRODUCTION: Brugada syndrome (BrS) is a genetic heart disease that predisposes individuals to malignant ventricular arrhythmias and sudden cardiac death (SCD). Although implantable cardioverter-defibrillators (ICDs) and quinidine are primary treatments, recurrent BrS-triggered cardiac ventricular arrhy...
INTRODUCTION: Sudden Cardiac Death (SCD) and Malignant Ventricular Arrhythmias (MVA) in patients with Hypertrophic Cardiomyopathy (HCM) occurs in up to 0.9%/ year. Identifying risk predictors for such an event is of paramount importance, considering the indication of Implantable Cardiodefibrillator (ICD)...
OBJECTIVE: Risk stratification of sudden cardiac death in patients with coronary artery disease is of great importance. We evaluated the association between ventricular repolarization and induction of malignant ventricular arrhythmias on electrophysiological study of patients with coronary artery disease...
INTRODUÇÃO: A morte súbita cardíaca é uma das complicações mais temidas em portadores de Miocardiopatia Hipertrófica (MCH) e geralmente decorre de eventos arrítmicos ventriculares. Acomete principalmente jovens e atletas e pode ser a primeira manifestação clínica da doença, justificando a im...
Hypertrophic cardiomyopathy (HCM) is characterized by unexplained left ventricular hypertrophy (LVH) and is one of the major causes of sudden cardiac death (SCD). An exon-targeted gene sequencing strategy was used to investigate the association of functional variants in sarcomeric genes (MYBPC3, MYH7 and...
