Action potential waveforms in WT and PPARγ mice. A, Representative in vivo monophasic action potential recordings from WT and PPARγ mice, mean RR interval 117 ms and 113 ms respectively. B, Graph of MAP recordings at 20%, 50% and 90% repolarization. WT: n=6; PPARγ: n=5. Mean ± SEM; **=p<0.01. C, Representative cardiomyocyte action potential waveforms from WT and PPARγ mice. D, Graph of APD at half-width, 20%, 50% and 90% repolarization. WT: n=24; PPARγ: n=39. Mean ± SEM; *** p<0.001.
