His Bundle Pacing: Techniques and Outcomes.
Traditional right ventricular pacing prolongs the electrical and mechanical activation of the heart, which reduces the pump function, and in selected patients may lead to pacing-induced heart failure. Pacing the His bundle preserves the normal or near-normal activation pattern of the ventricles that prevents the detrimental effects of right ventricular pacing. This review discusses the techniqu...
متن کاملPermanent, 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 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 کاملDetermination of His-Purkinje refractoriness in man with His bundle pacing.
Consistent His bundle pacing was accomplished in one of 60 consecutive patients. Intracardiac electrophysiologic studies in this patient revealed rapid atrioventricular nodal conduction (AH = 55 msec). While the relative refractory period of the His-Purkinje system as a whole determined by His bundle pacing (using the extrastimulus technique) was identical to that determined by atrial pacing, c...
متن کاملStep-wise Approach to Permanent His Bundle Pacing
There has been a recent upsurge of interest in permanent His bundle pacing, given increased understanding and appreciation of the role dyssynchronous ventricular activation plays in congestive heart failure and atrial fibrillation. Permanent His bundle pacing gives implanters the ability to avoid causing ventricular dyssynchrony in patients dependent on ventricular pacing, and can provide an al...
