Introduction: Focal disease in the main body of the His bundle (HB) is the cause for majority of the bundle branch block (BBB) patterns on EKG. Temporary distal HB pacing (HBP) has previously been shown to correct BBB in high number of patients. Anecdotal reports have confirmed abolition of BBB by permanent HBP. Hypothesis: The aim of our study is to report the incidence of correction of BBB during permanent HBP in patients undergoing pacemaker (PM) implantation. Methods: Permanent HBP was attempted in 185 patients referred for PM implantation. Pts with QRS duration (d) ≥110 ms and BBB were included in the study. Pts with normal QRS or CHB were excluded. HBP was performed using the Medtronic SelectSecure 3830 pacing lead. Baseline QRSd, paced QRSd, correction of BBB and HB pacing threshold were recorded. Results: Fifty patients met the inclusion-exclusion criteria. Mean age 73±12 yrs; men 65%, HTN 81%, DM 30%, CAD 38%, AF 42%, SSS 39%, AV disease 61%, RBBB 31, LBBB 14, IVCD 5). Permanent HBP was successful in correcting BBB in 42 (84%) patients. Underlying BBB was corrected by HBP in 29 of 31 (94%) patients with RBBB; 11 of 14 (79%) patients with LBBB; 1 of 5 (20%) patients with IVCD. Baseline QRSd improved from 141±15 ms to 124±17 ms. HBP threshold at implant was 1.5±1.3 V @ 0.5 ms. Conclusions: Permanent HBP corrected underlying BBB in the vast majority of patients with right or left BBB (40 of 45, 89%) compared to only 1 of 5 (20%) patients with IVCD. This confirms that focal disease in the main HB is the cause for BBB in the patients referred for PM implantation.

Abstract Background His-bundle pacing (HBP) is recognized as the most physiological way of pacing but with less study focused on electrical characteristics in different site. Purpose We aimed to evaluate the differences of pacing and echocardiographic parameters between atrial and ventricular side His-bundle pacing. Methods Patients who successfully underwent HBP implantation from September 2018 to August 2019 were retrospectively analyzed. All patients were assigned to atrial-side HBP (aHBP) group or ventricular-side HBP (vHBP) group according to the location of the His-bundle pacing lead, which was confirmed by two methods including postoperative echocardiography and visualization of tricuspid valve annulus (TVA). The pacing and echocardiographic parameters were compared between two groups during the procedure and at 3-month follow-up. Results A total of 71 bradycardia patients who successfully underwent HBP implantation and confirmed lead position were included. Among them, twenty-seven were assigned to aHBP group and the other 44 were assigned to vHBP group with no significant differences in baseline clinical characteristics between two groups. During the procedure, the proportion of selective HBP was significantly higher (77.8% vs. 11.4%; P<0.01) and the intra-procedural HV intervals was significantly longer (50.85±6.53 ms vs. 42.95±6.02 ms, P<0.01) in aHBP group than in vHBP group. The capture threshold in vHBP group was significantly lower than in aHBP group at implantation (0.92±0.22 V/1.0ms vs. 1.05±0.26 V/1.0ms, P=0.03) and remain significantly difference after 3-month follow-up (0.98±0.23 V/1.0ms vs. 1.15±0.44 V/1.0ms, P=0.03). The R-wave amplitude was significantly higher in vHBP group than in aHBP group at implantation (5.82±2.52 mV vs. 3.74±1.81 mV, P<0.01), and these differences still persisted during follow-up (5.88±2.51 mV vs. 3.67±1.61 mV, P<0.01). During 3-month follow-up, an increase in the capture threshold >1 V/1.0ms was seen in 2 cases in aHBP group while all patients remained stable in vHBP group. One patient developed a pocket hematoma in aHBP group compared to none in vHBP group. None of deterioration of tricuspid regurgitation and other procedure-related complications were observed during 3-month follow-up. Conclusions Ventricular side His-bundle pacing can achieve favourable pacing parameters including a lower pacing threshold and a higher R-wave amplitude than atrial side His-bundle pacing, which may be an ideal pacing strategy for patients in need of ventricular pacing.
