Table 2. Leads parameters of HBP and LBBP at the baseline and during the follow-up.

	24 h after implantation	Post 6 months	Post 12 months
Capture threshold, **P < 0.001 vs. HBP lead values. Sensing, &P < 0.001 vs. HBP lead values. Impendence, ##P < 0.01 and ###P < 0.001 vs. HBP lead values. HBP capture threshold increased after 6 months. HBP: His bundle pacing; LBBP: left bundle branch pacing.
