Right Bundle - Branch Block and Left Anterior
Right bundle-branch block occurred in 42.8% and left anterior hemiblock in 35% of 14 patients after surgical replacement of the tricuspid valve. The combination of RBBB with left anterior hemiblock is caused by injury to the branching portion of the bundle of His or more likely, by a lesion involving the pseudobifurcation. This study provides further proof that left anterior hemiblock may be pr...

A dom inant tenet in physio logy for m .ore t han half a century h as been the principle of homeostasis. The term was coined by W. B. Cannon (2) to describe the observation that physiological systems normally operate to reduce variability and to maintain a constancy of internal function. Accordingly, one might expect most any physiological variable, including heart rate, to return to its normal...
متن کاملLeft anterior hemiblock obscuring the diagnosis of right bundle branch block in acute myocardial infarction.
Thirty cases in which transient left anterior hemiblock (LAHB) obscured the diagnosis of right bundle branch block (RBBB) appearing during the first days of an acute myocardial infarction (AMI) are presented. Twenty-eight of the patients with AMI had a clear septal wall involvement, while the remaining two had an anterolateral and lateral wall AMI, respectively. These intraventricular conductio...
متن کاملLeft anterior hemiblock obscuring the diagnosis of right bundle branch block.
Three cases in which left anterior hemiblock (LAH) obscured the diagnosis of right bundle branch block (RBBB) are reported. The RBBB was incomplete in one case and complete or of high degree in the other two. The LAH was intermittent in two cases. In the three cases, the LAH abolished not only the S waves in leads I and aVL, but also the terminal R wave in Vl. The possibility that RBBB, complet...
متن کاملQT interval in right and left bundle-branch block.
The QT interval of the electrocardiogram is prolonged in right and left bundle-branch block. Since the QT interval is not prolonged outside the normal range due to myocardial disease alone, this lengthening of the QT interval is due to the conduction defect and is probably due to delayed depolarization (and thus repolarization) of the heart. There is, however, a significant difference in the QT...
