3.3 VT Acceleration
In 290 VT episodes of ATP therapies, occurrences of VT acceleration were
significantly associated with faster than with slower VTs (p = 0.006,
odds ratio, 1.04; average VT heart rate of episodes including
acceleration vs. no acceleration, 200 bpm, SD: 21 vs. 178 bpm, SD: 25).
In contrast, no significant difference was observed in acceleration
occurrence in other items (Table 5).
