His Bundle electrogram in bundle-branch block.
SUMMARY Because a great majority of patients with chronic complete heart block have bilateral bundle-branch lesions, it becomes important to recognize earlier degrees of bilateral bundle-branch block. The H-V interval in the His bundle electrogram during unilateral bundle-branch block reflects the conduction primarily through the contralateral bundle branch, and thus the His bundle electrogram ...
متن کاملLeft 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. ...
متن کاملLeft 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...
متن کاملCardiac pacing in left bundle branch/bifascicular block patients.
The primary concern in patients with bifascicular block is the increased risk of progression to complete heart block. Further, an additional first-degree A-V block in patients with bifascicular block or LBBB might increase the risk of block progression. Anesthesia, monitoring and surgical techniques can induce conduction defects and bradyarrhythmias in patients with pre-existing bundle branch b...
متن کاملHis bundle capture proximal to the site of bundle branch block: A novel pitfall of the para-Hisian pacing maneuver
Paced QRS morphology should be assessed to differentiate between complete loss of His bundle capture and loss of distal His bundle capture alone. This might be enough in patients with proximal right bundle branch block; however, in patients with proximal left bundle branch block, QRS morphology might be similar with loss of His bundle capture and with proximal His bundle capture. Introduction T...
