Objective: The purpose of this study was to compare differences in ventricular depolarization between these techniques using ultra-high-frequency electrocardiography (UHF-ECG). Methods: In patients with bradycardia, nsHBp, nsLBBp (confirmed concomitant left bundle branch [LBB] and myocardial capture), and LVSP (pacing in left ventricular [LV] septal position without proven LBB capture) were performed. Timings of ventricular activations in precordial leads were displayed using UHF-ECG, and electrical dyssynchrony (e-DYS) was calculated as the difference between the first and last activation. Duration of local depolarization (Vd) was determined as width of the UHF-QRS complex at 50% of its amplitude. Results: In 68 patients, data were collected during nsLBBp (35), LVSP (96), and nsHBp (55). nsLBBp resulted in larger e-DYS than did LVSP and nsHBp [– 24 ms (–28,–19) vs –12 ms (–16,–9) vs 10 ms (7,14), respectively, P <.001]. nsLBBp produced similar values of Vd in leads V5–V8 (36-43 ms vs 38-43 ms, P = NS in all leads) but longer Vd in leads V1–V4 (47–59 ms vs 41–44 ms, P <.05) as nsHBp. LVSP caused prolonged Vd in leads V1–V8 compared to nsHBp and longer Vd in leads V5–V8 compared to nsLBBp (44–51 ms vs 36–43 ms, P <.05) regardless of R-wave peak time in lead V5 or QRS morphology in lead V1 present during LVSP. Conclusion: nslbbp preserves physiological LV depolarization but increases interventricular electrical dyssynchrony. LV lateral wall depolarization during LVSP is prolonged, but interventricular synchrony is preserved.
