Table 4. Comparison of worsening of TR, MR and RVSP in tertile of ventricular pacing percentage.

	V pacing <30% (n = 147)	V pacing 30 to 99.5% (n = 133)	V pacing >99.5% (n = 149)	P-value
PMTR, n (%)	14 (9.5)	17 (12.8)	11 (7.4)	0.311
Worsening of MR, n (%)	23 (15.6)	24 (18.0)	17 (11.4)	0.282
RV systolic pressure, mmHg ± SD	30.7 ± 9.8	34.8 ± 14.1	34.4 ± 13.4	0.011

V pacing, Ventricular pacing percentage; PMTR, pacemaker-related tricuspid regurgitation; MR, mitral regurgitation; RV, right ventricle.
