This study evaluated the acute effect of dP/dtHemodynamic optimization may increase benefit from CRT. Typically, maximal left ventricular (LV) pressure rise dP/dtForty-one patients underwent CRT implantation followed by invasive PV loop measurements. The stimulation protocol included 16 LV pacing configurations using each individual electrode of the quadripolar lead with 4 atrioventricular (AV) delays. Conventional CRT was defined as pacing from the distal electrode with an AV delay of approximately 120 ms.Compared with conventional CRT, dP/dtPV-guided hemodynamic optimization in CRT results in approximately one-third SW improvement on top of conventional CRT, caused by a mechanism of enhanced VA coupling. In contrast, dP/dt |
