heal.abstractThis study examined the effects of different atrioventricular (AV) intervals, during AV sequential pacing, on hemodynamics and coronary blood flow in individuals with normal hearts. Left anterior descending artery blood flow velocity was measured, using intracoronary Doppler, in 17 normal individuals. Five pacing tests were applied in random order for 5 min, at 15 beats/min above the sinus rate. Four tests using AV sequential pacing with AV intervals of 175, 150, 100, and 50 ms, and one using atrial pacing were applied. Mean flow velocity was 21 +/- 9 cm/s, 20 +/- 9 cm/s, 17 +/- 7 cm/s, 17 +/- 7 cm/s, and 22 +/- 10 cm/s, respectively (F = 8.87, p = .00001). The hemodynamic effects of these 5 pacing tests were assessed in 8 different normal subjects. Isovolumic relaxation time constant and left ventricular systolic pressure decreased, whereas right atrial pressure increased during AV sequential pacing with short AV intervals. Thus, during short-term AV sequential pacing at rest, coronary blood flow in a normal left anterior descending artery decreases with short AV intervals.en
