Abstract:
Statistical analysis of 18,211 cases of electrocardiogram which were recorded in Chung-Ang University Hospital from January 1969 to December 162% of total cases(61% of male and 63% of female) and the incidence of normal electrocardiogram was decrease with aging. 2) Abnormal Q-wave was seen in 0.4% of total cases(0.5% of male and 0.3% of female) and the incidence of abnormal Q-wave was more common over 50 years of age. 3) Left axis deviation was seen in 1.1% of total cases(1.4% of male and 0.9% of female) and the incidence of left axis deviation was more common over 50 years of age. Right axis deviation was seen in 0.3% of total cases(0.3% of male and 0.4% of female) and the incidence of right axis deviation was more common under 30 years of age. 4) Left ventricular hypertrophy was seen in 3.6% of total cases(4.8% of male and 2.5% of female) and the incidence of right ventricular hypertrophy was more common under 30 years of age. 5) ST-segment depression was seen in 2.0% of total cases(2.2% of male and 1.9% of female) and the incidence of ST-segment depression was increased with aging. 6) T-wave inversion was seen in 1.6% of total cases (1.5% of male and 1.7% of female) and the incidence of T-wave inversion was increased with aging. 7) Atrioventricular block was seen in 1.4% of total cases(1.8% of male and 1.0% of female) and the incidence of atrioventricular block was more common over 50 years of age. 8) Incidence of complete left bundle branch block was 0.2% and was more common overs 60 years of age. Incidence of complete right bundle branch block was 1.1% and the incidence was more common over 50 years of age. Incidence of incomplete right bundle branch block was 3.0% and the incidence was more common under 40 years of age. 9) The incidence of premature beat was 2.7% of total cases, atrial fibrillation 1.5%, supraventricular tachycardia 0.2%, sinus tachycardia 7.5%, sinus bradycardia 2.2% and sinus arrhythmia 2.3%. 10) Low voltage was ssen in 3.8% of total cases and the incidence of low voltage was more common over 50 years of age.
