Ventricular Tachycardia and Early Fibrillation in Patients With Brugada Syndrome and Ischemic Cardiomyopathy Show Predictable Frequency-Phase Properties on the Precordial ECG Consistent With the Respective Arrhythmogenic Substrate
BACKGROUND Ventricular fibrillation (VF) has been proposed to be maintained by localized high-frequency sources. We tested whether spectral-phase analysis of the precordial ECG enabled identification of periodic activation patterns generated by such sources. METHODS AND RESULTS Precordial ECGs were recorded from 15 ischemic cardiomyopathy and 15 Brugada syndrome (type 1 ECG) patients during i...
متن کاملEffect of Alcohol on Heart: Case Presentation of Two Alcoholic Patients with Alcoholic Cardiomyopathy
Background: Alcohol consumption has multiple side effects on heart which can be divided to six subgroups: Heavy alcohol drinkers (80 g/day alcohol consumption) are most susceptible to cardiac complications. The aim of this study was to review alcohol side effects on heart and two present two alcoholic patients with alcoholic cardiomyopathy. Case report: Case A: A 52 year-old man presented with ...
متن کاملDiagnostic Dilemmas: Overlapping Features of Brugada Syndrome and Arrhythmogenic Right Ventricular Cardiomyopathy
Arrhythmogenic right ventricular cardiomyopathy (ARVC) and Brugada syndrome are distinct clinical entities which diagnostic criteria exclude their coexistence in individual patients. ARVC is a myocardial disorder characterized by fibro-fatty replacement of the myocardium and ventricular arrhythmias. In contrast, the Brugada syndrome has long been considered a functional cardiac disorder: no gro...
متن کاملRight bundle branch block, right precordial st-segment elevation, and sudden death in young people.
BACKGROUND Patients with the ECG pattern of right bundle branch block and right precordial ST-segment elevation may experience sudden death in the setting of either arrhythmogenic right ventricular cardiomyopathy (ARVC) or a functional electrical disorder such as Brugada syndrome. METHODS AND RESULTS Among a series of 273 young (</=35 years) victims of cardiovascular sudden death who were pro...
متن کاملThe use of noninvasive ECG imaging for examination of a patient with Brugada syndrome
Introduction Brugada syndrome (BrS) is an inherited cardiac arrhythmia syndrome associated with electrocardiography (ECG) patterns characterized by incomplete right bundle branch block and ST segment elevation in the anterior precordial leads, correlated to an increased risk of sudden cardiac death. Genetic substrate, ECG manifestation, and risk of arrhythmia in patients with BrS vary considera...
