  • Continuous data are presented as means±SD and categorical data as the number of cases (% of the total study population). The ECG risk score consisted of five ECG abnormalities: heart rate >80 bpm, PR duration >220 ms, QRS duration >110 ms, LVH and T-wave inversion.

  • bpm, beats per minute; LVH, left ventricular hypertrophy.
