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 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 کاملAutopsy analysis of the implantation site of a permanent selective direct his bundle pacing lead.
To date, there has not been direct visualization of the anatomic location of direct His bundle pacing (DHBP) leads in the human heart. The absence of such data has contributed to disagreement about the location of DHBP leads with respect to the plane of the tricuspid valve.1,2 We present an autopsy study of a patient who had previously had a DHBP lead implanted, showing unequivocally that the l...
متن کاملNormal conduction intervals and responses in sixty-one patients using His bundle recording and atrial pacing.
In the present study, His bundle electrograms (H) were recorded in 61 patients without evidence of conduction disease on the surface el ‘cfrocardiogram, in order to establish the normal range of conduction intervals. The conduction intervals (in msec) were as follows (mean ± 2 SD): P-H 1 19 ± 1 19 ± 38; P-A 27 ± 18; A-H 92 ± 38 and H-V 43 ± 12. Afrial pacing was performed in 45 patients. Thirty...
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 ...
