Abbreviation: ECG, electrocardiogram; APC, atrial premature complex; HR, hazard ratio; CI, Confidence Interval.

Multivariate-Adjusted for Model 1 (age and gender), Model 2 (age, gender, body mass index, smoking habit, drinking habit, hypercholesterolemia, diabetes mellitus, systolic blood pressure, serum creatinine) and Model 3 (Model 2 + other ECG findings).
