Right ventricular apex and mid-septum pacing had similar pacing-induced cardiomyopathy rates; preoperative left ventricular end-systolic diameter and paced QRS duration were independent predictors.
Does 'true' mid-right ventricular septum pacing reduce the incidence of pacing-induced cardiomyopathy compared to right ventricular apex pacing?
Mid-right ventricular septum pacing does not significantly reduce the incidence of pacing-induced cardiomyopathy compared to right ventricular apex pacing, while preoperative LV end-systolic diameter and paced QRS duration are independent predictors of PICM.
There was no significant difference in the incidence of pacing-induced cardiomyopathy between right ventricular apex pacing group and OpenCurlyQuote;true CloseCurlyQuote; mid-right ventricular septum pacing group. The preoperative left ventricular end-systolic diameter and paced QRS duration were independent predictors of PICM.
Yoshiyama et al. (2022) studied this question. Right ventricular apex and mid-septum pacing had similar pacing-induced cardiomyopathy rates; preoperative left ventricular end-systolic diameter and paced QRS duration were independent predictors.
