Effects of sitagliptin on post-rest potentiation contraction (PRPC) of left atrium (LA). An example and average data (n = 7) show that the increment of PRPC was divided by baseline contractile forces to present as D/baseline (%). In WKY, the percentile increment of PRPC after 30 or 120 s pause was significantly larger than that after 10 s pause. But the PRPC did not increase further after 120 s pause than that after 30 s pause. Treatment with sitagliptin significantly diminished the PRPC of WKY rats with 10, 30 and 120 s pause. In SHR, the PRPC was significantly smaller than that of WKY. The treatment of sitagliptin cannot significantly change the PRPC of SHR with 10, 30 and 120 s pause. * p < 0.05, ** p < 0.01 vs. the control (WKY).
