a Heart rate (HR), beats per minute (BPM) (p = 0.0005) (n = 6); b Representative ECG of 16-week-old mice (time frame, 100 ms); c Representative action potential image of 16-week-old mice cardiomyocyte (time frame, 100 ms); d, e Action potential repolarization duration at 50% and 90%, respectively (two-tailed Welch test: APD90 p = ns, APD50 p = 0.0148) (WT n = 10, KO n = 18, N = 3). p-value: unpaired two-tailed t-test and two-tailed Welch test performed. Data are represented as mean ± SEM.
