WebDec 15, 2024 · Chronic RVP was defined as a RV pacing burden of at least 50% pacing on the pre-CRT upgrade device check. All CRT device implantations were performed via a transvenous access targeting a lateral or posterolateral vein for the left ventricular lead position. RV leads were positioned in the RV apex or septum. WebOct 5, 2015 · Pacing from the right ventricular apex (RVA) can cause electrical and mechanical dyssynchrony resulting in long-term left ventricular (LV) dysfunction. 1 Therefore, alternative RV pacing sites have been explored to produce a more ‘physiological’ LV activation pattern.
