Table 2 Effect of Biv Pacemaker Optimization on Echo Doppler Variables at Baseline Heart Rate

From: Shortening of atrioventricular delay at increased atrial paced heart rates improves diastolic filling and functional class in patients with biventricular pacing

Echo Doppler Variables Baseline Optmial P Value
LV Diastolic Filling Time (ms) 396 ± 75 420 ± 63 0.016
LVOT VTI (cm) 17.5 ± 4.8 19.4 ± 5.2 < 0.001
LV ejection time (ms) 287 ± 40 298 ± 36 < 0.001
