Data are presented as means±standard deviations for the normally distributed continuous variables and median and interquartile (25th–75th) ranges for the continuous variables with a skewed distribution. To compare the continuous data, we used the one-way analysis of variance or the nonparametric Kruskal–Wallis H test, as appropriate. PA - the time interval from the onset of the P wave on the surface ECG to the peak of a’ in tissue Doppler imaging; RV - right ventricle
