The electromechanical dyssynchrony associated with right ventricular pacing (RVP) has been found to have adverse impact on clinical outcomes. Several studies have Conclusion: We demonstrated longer RV lead sensing latency (1) through PSA than through pacemaker, resynchronization therapy (2) in RBBB than in narrow-QRS, and (3) in Medtronic pacemakers compared with The adaptivCRT (aCRT) algorithm was developed to provide continuous optimization and synchronized left ventricular (LV) pacing to right ventricular (RV) sensing.1–3

Abstract Ventricular sensing relies on the analysis of a local intracardiac electrogram in reference to the QRS on the surface electrocardiogram. If both signals do not coincide in time, there is a

Background: Pacemaker implantation involves intraoperative testing of ventricular sensing using a device called a pacing system analyzer (PSA). The value obtained is expected to correspond Medtronic pacemakers compared with In to Conclusion: We demonstrated longer RV lead sensing latency (1) through PSA than through pacemaker, (2) in RBBB than in narrow-QRS, and (3) in Medtronic pacemakers compared with

In contrast to standard dual-chamber pacemakers, biventricular pacemakers aim to maximize ventricular pacing to deliver the highest possible dose of cardiac resynchronization If the latency period between left (LV) and right (RV) stimulation is about 40 ms or more, then device related two stimulus artefacts can be identified on the ECG (red highlight). With dual chamber pacing, Loss of pacing capture of the right or left ventricle as well as prolongation of the device-defined LV latency can be automatically unmasked in Biotronik CRT-D devices by
