Overcoming left bundle branch block by permanent His bundle pacing: Evidence of longitudinal dissociation in the His via recordings from a permanent pacing lead
Introduction Narrowing of the QRS and overcoming left bundle branch block (LBBB) with His bundle pacing (HBP) has been previously described. We present the first 2 reported cases of left bundle branch (LBB) delay with evidence of a split His electrogram during unipolar mapping from the tip of the His bundle (HB) lead during pacemaker implantation. These findings suggest that the site of LBB del...
متن کاملHis 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 کاملAcute His Bundle Injury during Permanent His Bundle Pacing: Mechanistic Insights into Intra- Hisian Block
Permanent His bundle pacing (HBP) is a physiological alternative to right ventricular pacing. Acute injury to the His bundle can occur during permanent HBP in the form of transient or permanent bundle branch blocks. Observations of mechanical injury to the His bundle during HBP lead fixation and electrophysiological response to HBP provides additional mechanistic insights into the pathology of ...
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...
