Values are represented as mean ± SD.

N = 51 for SR (n = 14 for intracardiac measurements), n = 51 for AAVB (n = 26 for intracardiac measurements).

ARI, activation recovery interval; LVAT, left ventricular activation time; LV STV, Short-term variability of repolarization; MAPD, monophasic action potential duration; RV, right ventricle; RVAT, right ventricular activation time; RV STV, short-term variability of repolarization; SR, sinus rhythm; Tp-e, time between the peak and the end of the T-wave.

*P < 0.001 vs. sinus rhythm.

**P < 0.05 vs. sinus rhythm.

***P < 0.01 vs. sinus rhythm.
