Permanent, direct His-bundle pacing: a novel approach to cardiac pacing in patients with normal His-Purkinje activation.
BACKGROUND Direct His-bundle pacing (DHBP) produces synchronous ventricular depolarization and improved cardiac function relative to apical pacing. Although it has been performed transiently in the electrophysiology laboratory and persistently in open-chested canines, permanent DHBP in humans has not been achieved. METHODS AND RESULTS A total of 18 patients aged 69+/-10 years who had a histor...
متن کاملThe potential and reality of permanent his bundle pacing.
Right ventricular apex pacing can have deleterious effects. Our aims were to investigate how many patients referred for permanent pacing were suitable candidates for permanent His bundle pacing, and to determine the proportion in whom such pacing was successful. All cases of suprahisian block and most cases of infrahisian block (71.4%) were corrected by temporary His bundle pacing. However, per...
متن کاملOvercoming 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 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 کامل[Permanent His-bundle pacing in patients with infra-Hisian atrioventricular block].
INTRODUCTION AND OBJECTIVES Permanent His-bundle pacing is effective in patients with supra-Hisian atrioventricular block. We report our experience in patients with infra-Hisian atrioventricular block. METHODS The study involved selected patients referred for syncope and intraventricular conduction disturbance, infra-Hisian atrioventricular block, with left ventricular dyssynchrony and no cor...
