Zusammenfassung:[...]the comparison of LBBAP and BiVP-epi on DVR was performed in the current study, and postoperative DVR were statistically significantly lower in LBBAP patients. Since post-implant repolarization parameters have been identified as the independent predictors of appropriate implantable cardiac defibrillator therapy in CRT patients,[2] the better repolarization stability in LBBAP group than BiVP-epi group may suggest lower VAs and low SCD risks in the former group. According to these results, it may be more prudent to weigh the risk of DVR deterioration against the benefit of better depolarization synchrony concerning CRT optimization, especially for those with high SCD risks. [...]LBBAP provided better repolarization status immediately after the implantation than BiVP-epi, and whether the incidence of VAs and/or SCD was lower in the former group remains to be further studied.
