BACKGROUND Patients with an acute anterior ST-segment elevation myocardial infarction and right bundle-branch block (RBBB) have a high mortality risk, which may be stratified by early ECG changes. METHODS AND RESULTS In the Hirulog Early Reperfusion Occlusion (HERO-2) trial, 17 073 patients with acute myocardial infarction (AMI) within 6 hours of symptom onset were treated with streptokinase ...
OBJECTIVES This study sought to test the hypothesis that right bundle branch block (RBBB) patients have larger scar size than left bundle branch block (LBBB) patients do. BACKGROUND A proximal septal perforating branch of the left anterior descending (LAD) coronary artery most commonly perfuses the right bundle branch and left anterior fascicle, but not the left posterior fascicle. Thus, prox...
Right bundle branch block (RBBB) is usually considered almost unavoidable after repair of tetralogy of Fallot (TOF). By modifications of the standard technique, its frequency has been decreased to 32% in a series of 100 consecutive patients. These modifications are: (1) a very short right ventricular incision, avoiding the ventriculotomy-induced RBBB pattern; (2) an infundibular resection limit...
AIMS The aims of this study were: (i) to characterize consecutive cardiac resynchronization therapy (CRT) recipients with right bundle branch block (RBBB) in comparison with left bundle branch block (LBBB) and (ii) to identify independent predictors of long-term outcome among CRT recipients with RBBB. The presence of RBBB has been associated with poorer prognosis after CRT compared with LBBB; h...
We examined the characteristics, long-term follow-up, and prognosis of right bundle branch block (RBBB) detected on a routine ECG in men with no apparent heart disease. During the 29-year period, 59 cases of RBBB were observed in men with a mean age of 44.4 ± 1.9 years. Because marked right or left axis deviation may identify cases with concomitant involvement of the left bundle branch system, ...
A 59-year-old hypertensive man presented to the emergency department with an episode of dizziness without syncope. A surface 12-lead electrocardiogram (ECG) showed sinus rhythm at 82 bpm with a 2:1 complete right bundle branch block (RBBB) pattern (Fig. 1). The patient presented a full spontaneous recovery and was subsequently discharged and referred for ambulatory diagnostic work-up. Echocardi...
right bundle branch block (rbbb) is considered as an important predictor of poor outcome in patients with acute myocardial infarction, but the prognostic implication of rbbb in patients with suspected coronary artery disease (cad) is unclear. furthermore, the association between rbbb and incidence of cad also its influence on the severity of stenosis in coronary arteries has not been establishe...
The exact prevalence and nature of cardiac involvement in facioscapulohumeral muscular dystrophy (FSHD) is unknown. Nevertheless, the current opinion is that symptomatic cardiac disease is rare. We performed a cardiac screening [electrocardiogram (ECG) and echocardiography in the event of ECG abnormalities] in 75 genetically confirmed, ambulant FSHD patients without cardiac symptoms, with an ei...
AIMS Intraventricular conduction defects (IVCDs) can impair prognosis of heart failure (HF), but their specific impact is not well established. This study aimed to analyse the clinical profile and outcomes of HF patients with LBBB, right bundle branch block (RBBB), left anterior fascicular block (LAFB), and no IVCDs. METHODS AND RESULTS Clinical variables and outcomes after a median follow-up...
