Abstract

A device is connected to electrode leads which performs intracardiac impedance measurements, conducts a transient pacing protocol, analyses the impedance measurements, and generates an LV lead position quality factor. The transient pacing protocol includes a repeated change (“transitions”) between ventricular intrinsic rhythm and biventricular paced rhythm and may also include a variation of the atrioventricular delay (AVD) and/or the interventricular delay (VVD). The quality factor expresses the degree to which hemodynamic properties have improved due to BiV stimulation for the current LV lead position compared to intrinsic ventricular rhythm.
