WebThe averaged QTc in the ventricular paced rhythm was then compared with the non-ventricular-paced QTc for individual subjects. Results: At a mean spontaneous heart rate of 66 bpm (SD ±8), the mean difference in QTc between the ventricular paced and nonpaced QRS was 48.27 ms (95% CI = 32-64.6 ms, p < 0.001).
