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 کاملSuccessful resynchronization by permanent His-bundle pacing in a patient with pacing-induced cardiomyopathy
Right ventricular (RV) pacing has been reported to result in ventricular dyssynchrony, heart failure, and increased mortality. Pacing associated deterioration of left ventricular (LV) systolic function has been termed pacing-induced cardiomyopathy (PICM). While upgrading to biventricular pacing (BiVP) is an effective therapy for PICM, permanent His-bundle pacing (HBP) can be a physiological alt...
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 کاملNormalization of bundle branch block patterns by distal His bundle pacing. Clinical and experimental evidence of longitudinal dissociation in the pathologic his bundle.
Clinical and experimental observations in which bundle branch block patterns (BBBP) in ECG leads were normalized by distal His bundle (H) pacing are reported. The clinical material includes four patients with acute right BBBP secondary to anterior wall myocardial infarction and three patients with chronic left BBBP. Six of the seven patients had a prolonged H-V interval (60-85 msec) including t...
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...
