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. ...

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...
متن کاملPosterior myocardial infarction and complete right bundle- branch block.
We describe two patients with posterior myocardial infarction (PMI) with unusually atypical clinical presentations and cardiac enzymatic profiles, but with the abrupt development of complete AV block in patient 1, and Mobitz II second-degree AV block with paroxysmal phases of higher degrees of AV block in patient 2, and mitral regurgitation leading to symptomatic pulmonary congestion. Also, bot...
متن کاملAcute myocardial infarction and left bundle branch block.
Complete left bundle branch block often masks old as well as acute myocardial infarctions. However, a diagnosis of acute myocardial infarction in the presence of complete left bundle branch block can be made when the acute injury current is large enough to modify the secondary repolarization abnormalities of left bundle branch block. Under these circumstances the classical ST-T changes of an ac...
متن کاملThe anatomic substrate of complete left bundle branch block.
SUMMARY The conduction systems of eight cases diagnosed clinically as having complete left bundle branch block (LBBB) were serially sectioned. Left axis deviation was present in six and normal axis in two. In all cases there was evidence of ischemia of the myocardium and left bundle branch (LBB) in various parts of the coronary circulation. In all cases, the LBB showed pathologic change at its ...
