Ventricular pacing burden
In comparing ventricular pacing burden between groups, there was no
difference in likelihood to require pacing greater than 50% of the time
(HD 36/190 counts, control 41/185 counts, p = 0.441). By quartile, HD
patients more frequently paced in the range of 26-50% of the time (HD
21/190 counts vs 1/185 counts, p < 0.001, Figure 2 ),
but no other differences between groups by quartile were found.
