In the 2001 edition of the textbook Heart Disease (1) Brugada syndrome is defined as a “distinct form of idiopathic ventricular fibrillation (VF) in which patients have right bundle branch block (RBBB) and ST elevation in the anterior precordial leads without evidence of structural heart disease.” Although patients with such characteristics were described before the Brugada brothers reported th...

Using intracardiac recording techniques, His bundle (H) and right ventricular apical (RVA) electrograms were recorded in 16 patients with a postoperative electrocardiographic pattern of right bundle branch block (RBBB). Their ages ranged from 5 to 12 years (mean 6.9 years) at surgery and the follow-up period was 1 to 7 years (mean 2.7 years). All were asymptomatic and in sinus rhythm at the tim...

Introduction Verapamil-sensitive fascicular ventricular tachycardia (VT) is the commonest form of idiopathic left ventricular tachycardia (ILVT). The characteristic diagnostic features of fascicular ILVT include: (i) induction with atrial pacing, (ii) right bundle branch block (RBBB) with left-axis deviation morphology during VT, (iii) absence of structural heart disease, and (iv) verapamil sen...

BACKGROUND The purpose of this study was to systematically study diagnostic and prognostic electrocardiographic (ECG) characteristics of arrhythmogenic right ventricle dysplasia/cardiomyopathy (ARVD/C). METHODS AND RESULTS The patient population included 50 patients with ARVD/C (27 males, 23 females; mean age 38+/-15 years). We also analyzed the ECG of 50 age- and gender-matched normal contro...

During reciprocating tachycardia in patients with accessory atrioventricular pathways, the observation of changes in ventriculoatrial (VA) intervals with bundle branch block (BBB) aberration has been used to localize the site of the pathway and prove the participation of the pathway in the tachycardia. In this report we present the changes observed during BBB in 93 patients with single atrioven...

This report concerns the task of electrocardiographic (ECG) diagnosis and quantitation of left ventricular hypertrophy (LVH) in patients with right bundle branch block (RBBB). In 36 patients with RBBB the left ventricular mass (LVM) of each patient was independently known from quantitative biplane angiography. Two ECG techniques, standard 12-lead ECG and multiple dipole electrocardiography (MDE...

Introduction/Objective. Cardiovascular disease is one of the most common comorbidities among subjects with chronic obstructive pulmonary (COPD). The aim this study to evaluate electrocardiogram (ECG) parameters and mortality predictors in COPD patients. Methods. A total 835 consecutive patients were included. classified suffer from if forced expiratory volume first second (FEV1) vital capacity ...

Varying degrees of functional conduction disturbances occurred in two patients with old IWMl during aberration of spontaneous, or induced, premature atrial contractions. Ventricular complexes transitional in form between those having normal (control) intraventricular conduction and those showing the most advanced grades of LBBB, LAH, LPH were interpreted as "incomplete* forms of the latter. Inc...

It has been postulated that postoperative right bundle branch block (RBBB) may be produced by conduction block at any of several sites. In this study the site of block and resultant pattern of ventricular activation were documented in 20 patients in whom RBBB developed during repair of congenital cardiac defects. Intraoperative epicardial and endocardial mapping and recording from the right ven...

BACKGROUND Left dominant arrhythmogenic cardiomyopathy (LDAC) is a rare condition characterised by progressive fibrofatty replacement of the myocardium of the left ventricle (LV) in combination with ventricular arrhythmias of LV origin. CASE PRESENTATION A thirty-five-year-old male was referred for evaluation of recurrent sustained monomorphic ventricular tachycardia (VT) of 200 bpm and right...
