His Bundle Recordings in Patients with Bundle Branch Block and Transient Neurologic Symptoms

His bundle recordings in patients with bundle branch block and transient neurologic symptoms.

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 ...

Transient Bundle-branch Block.

IN a recent survey of 167 patients with buIndle-branch l)lock 1 10 in.stances of transient bundle-branch block were discovered. Since the completion of this study four more patients with this condition have been encountered. These 14 patients represent the subjects of this report. Transient bundle-branch block is defined as an intraventricular conduction defect that subsequently returns, if onl...

Contribution of His bundle recordings to analysis of abnormal beats with right bundle-branch block--superior axis pattern.

His bundle electrograms were recorded in four patients with ectopic rhythms showing a right bundle-branch block superior axis pattern. In one case what appeared to be a slow idioventricular rhythm was identified as a His bundle rhythm with transient right bundle-branch block and left anterior hemiblock. The second patient had an idioventricular tachycardia. H deflections were not seen in front ...
