Does acute biventricular pacing increase coronary blood flow velocity?
Acute biventricular pacing improves coronary blood flow velocity by enhancing the diastolic backward decompression wave, linking improved left ventricular mechanics to coronary hemodynamics.
When biventricular pacing improves LV contraction and relaxation, it increases coronary blood flow velocity, predominantly by increasing the dominant diastolic backward decompression (suction) wave.
