Coronary Artery Anatomy in Left Bundle Branch Block

Coronary artery anatomy in left bundle branch block.

Detecting coronary artery disease in left bundle branch block.

t eft bundle branch block (LBBB) creates a problem in etecting spontaneous or inducible myocardial ischemia or ven acute myocardial infarction despite a modification of he ST-segment criteria (1). Although LBBB could be an solated electrocardiographic abnormality, it could also be, specially in elderly patients, associated with other cardiac iseases such as coronary artery disease (CAD), cardio...

Left Bundle Branch Block

Coronary angiography, cine left ventriculography, and the cardiovascular hemodynamics of 24 patients with left bundle branch block were studied. Seven patients were found to have significant coronary artery disease, always severe. Five had cardiomyopathy and seven had valvular disease. Only those with coronary artery disease or cardiomyopathy had abnormal left ventricular contraction patterns. ...

Left bundle branch block.

A RECENT STUDY of the prognosis of patients with left bundle branch block (L.B.B.B.) suggested that life expectancy was extremely short (Smith and Hayes 1965). While in general L.B.B.B. has a sinister reputation, we have been struck by a few individuals who have survived many years with L.B.B.B., and we thought an analysis of some of the material available at the Royal Victoria Hospital, Belfas...

Baseline left bundle branch block with right bundle branch escape complexes in a patient with coronary artery disease, presents like an alternating bundle branch block: a case report

Alternating bundle branch block (ABBB) is a less commonly encountered phenomenon with the advent of re-perfusion therapy for acute myocardial infarction. ECGs simulating the appearance of an ABBB need to be carefully analysed. We present an ECG showing a baseline Left Bundle Branch Block(LBBB) progressing to a high grade AV block with escape complexes having a Right Bundle Branch Block (RBBB) m...
