TABLE 3.
Comparison of ventricular arrhythmias and major adverse events during the follow‐up period among the different pacing groups
| Parameters | HBP (n = 13) | Control (AAI mode) (n = 14) | RVP (n = 14) | p‐value |
|---|---|---|---|---|
| All‐cause death | 0 (0%) | 1 (7.1%) | 2 (14%) | .363 |
| HF hospitalization | 0 (0%) | 0 (0%) | 2 (14%) | .132 |
| Ventricular arrhythmias | 2 (15%) | 1 (7.1%) a | 7 (50%) | .020 |
| Sustained ventricular arrythmias (>30 s) | 0 (0%) | 0 (0%) | 0 (0%) | n/a |
| Non‐sustained ventricular tachycardias (>5 s) | 3 (23%) | 1 (7.1%) a | 7 (50%) | .020 |
| Total adverse events | 2 (15%) b | 2 (14%) a | 11 (79%) | <.001 |
| Non‐RVP mode (HBP and control) (n = 27) | RVP mode (n = 14) | p‐value | ||
| Ventricular arrhythmias | 3 (11%) | 7 (50%) | .017 | |
| Total adverse events | 4 (15%) | 11 (79%) | <.001 | |
Note: The data are presented as numbers (%). Differences in the outcomes among the groups were analyzed using the chi‐squared test.
Abbreviations: HBP, his‐bundle pacing; HF, heart failure; RVP, right ventricular pacing.
