Using a community-based population of patients with acute myocardial infarction (AMI), we sought to: (1) determine the prevalence of bundle branch block (BBB) on the presenting electrocardiogram (ECG), (2) compare the clinical characteristics and the treatment administered to patients with and ...
The increased risk of death was also present when LBBB (HR 1.121, 95% CI 1.042–1.207) and RBBB (HR 1.187, 95% CI 1.045–1.348) were considered individually. There was no difference in risk between LBBB and RBBB (P for interaction = 0.533). Other outcomes including sudden death, ...
ECG = electrocardiogram; HF = heart failure; IVCD = intraventricular conduction delay; LBBB = left bundle branch block; LVEF = left ventricular ejection fraction; NS = not stated; QRS measurement = method used to determine QRS duration; RBBB = right bundle branch block; Year = year of public...
We have reported in the past on an ECG appearance suggestive of an acute PMI in the presence of complete RBBB, which consists of the acute development of tall R waves involving the early part of the QRS complex, and tall T waves, both noted in the right precordial leads. The 2 ...
(A) Hybrid machine learning approach (B) Flow of data and analyses performed in this study. LBBB: left bundle branch block, RBBB: right bundle branch block, AVB: atrioventricular block. Survival analysis in the derivation dataset, phenogroup B has a markedly worse prognosis. (A) whole CODE ...
