Abstract: To explore some variation about normal electrocardiograph (ECG). Methods 6800 people aged 17～40 who hadhealth physical examination in our hospital from 1993～2011 were reviewed. Results The ECG of 4640 (68.24%) people are normal, 136(2%) were abnormal. The rest 2024 (29.76%) people probably had some ECG variation as follows: shorter PR interval (PR<0.12 s); PⅡ upsidedown; heart rate (HR): 40～60 beats/min, HR: 100～110 beats/min; incomplete right bundle branch block (ICRBBB); left ventricular hypertrophy(LVH); abnormal Q; RV1～RV5 amplitude were not increasing; SⅠSⅡSⅢ; STV3～V6 elevation>0.3～0.5 mV; Heart electrical axis is somewhatdeviation and heart position is somewhat shift; occasional superventricular premature beats or ventricular premature beats, etc. Theywere finally diagnosed as normal healthy people after 3～6 months follow-up with ultrasonic cardiogram (UCG), Holter and chest X rays,etc. Conclusion These abnormal ECG beyond normal ECG diagnosis standards are variation of normal ECG in health people.
