Table 2. Comparison of ECG parameters between groups.

Values are presented as mean±SD and median (interquartile range).

Pmax: P-wave maximum duration; Pmin: P-wave minimum duration; Pd: P-wave dispersion; QTd: QT dispersion; QTcd: corrected QT dispersion; TpTe: T-peak to T-end; TpTec: corrected TpTe
