Table 4. Graft Rejection according to PR Interval at 1 Year after HT.

	The change of graft rejection from 1 month to 1 year following HT
	No change in GR	No evidence of GR	New onset of GR	Resolving of GR	p value
PR interval (<153 ms*)	5 (41.7)	8 (61.5)	2 (18.2)	11 (73.3)	0.033
PR interval (≥153 ms)	7 (58.3)	5 (38.5)	9 (81.8)	4 (26.7)

HT, heart transplantation; GR, graft rejection; RBBB, right bundle branch block.

Values are presented as n (%). p value by chi-square test.

^*153 ms: median value of PR interval in overall study population at 1 year following HT.
