The incidence of major abnormal ECG were 7.3% for STT changes, 5.6% for sinus tachycardia, 4.4% for sinus arrhythmia, 3.4% for ventricular premature beats, 2.0% for bundle branch block and 1.8% for atrial premature beats; Apart from preexcitation syndrome, the incidence of abnormal ECG for male was higher than that of female;Most of abnormal ECG increased with age. A few abnormal ECG such as sinus tachycardia, sinus arrhythmia, sick sinus syndrome decreased with age. The incidence of sinus bradycardia and preexcitation syndrome were bail shape with age. Half of abnormal ECG adults had at least two abnormal ECG, such as STT changes combined with ventricular premature beats or bundle branch block.
