EF: ejection fraction; LVEDD: left ventricular end‐diastolic diameter; LVESD: left ventricular end‐systolic diameter; PVC cycle length: coupling interval of the ventricular extrasystole; Post PVC: cycle length after the PVC; QT: QT interval; QTdis: QT interval dispersion; SDNN: standard deviation of the RR‐intervals; RMSSD: root mean square of the standard deviation; PNN 50: percent of intervals outside 50 ms of the mean; P value < 0.05 is considered as significant.
