As a backup lead in right ventricle (RV) is often used in His-bundle pacing (HBP) implants, in sinus rhythm patients the His lead is connected to the left ventricular (LV) port of a CRT device. In current devices, the backup pacing will be delivered 100% of time due to cross-channel ventricular refractory periods. Beyond an impact on battery, unnecessary RV pacing could find excitable tissue and capture a portion of the myocardium tissue potentially reducing the benefits of physiological HBP as shown in this case report where the switch from biventricular to LV-only pacing improved acute and 2-month echocardiography parameters.

Abstract
As a backup lead in right ventricle (RV) is often used in His-bundle pacing (HBP) implants, in sinus rhythm patients the His lead is connected to the left ventricular (LV) port of a CRT device. In current devices, the backup pacing will be delivered 100% of time due to cross-channel ventricular refractory periods. Beyond an impact on battery, unnecessary RV pacing could find excitable tissue and capture a portion of the myocardium tissue potentially reducing the benefits of physiological HBP as shown in this case report where the switch from biventricular to LV-only pacing improved acute and 2-month echocardiography parameters.File in questo prodotto:
