Analysis of the data for ventricular stimulation threshold, impedance, and R wave
| Intraoperation | Last follow-up | P value | |
|---|---|---|---|
| Ventricular stimulation threshold(V) | 1.34 ± 0.72 | 1.37 ± 0.81 | p = 0.933 |
| Impedance (Ω) | 366.7 ± 88.0 | 331.9 ± 95.9 | p = 0.327 |
| R wave(mV) | 12.3 ± 3.5 | 11.4 ± 4.9 | p = 0.635 |
