방실차단 및 심실내전도장애에 관한 통계적 고찰 = A Statistical Study on the Atrioventricular Block and Intraventricular Conduction Disturbance

다국어 초록 (Multilingual Abstract)

A statistical study was done on atrioventricular block and intraventricular conduction disturbance in 127 cases taken on 1,761 patients subjected to electrocardiographic examination.
The results were as follows
1. Total incidence of conduction disturbance was 7.21%, atrioventricular block was 2.67% and intraventricular block was 4.54% of total patients. Among of these, first degree atrioventricular block was 2.44% which was the most common occurred one, and complete right bundle branch block(2.33%), incomplete right bundle branch block (1.13%), left anterior hemiblock(0.74%), third degree atrioventricular block and left bundle branch block(each 0.17%), bifascicular block(0.11%), second degree atrioventricular block and left posterior hemiblock(erach 0.06%) in the order of frequency.
2. The ratio of male to female was 1.2:1 for atrioventricular block and 1.4:1 for intraventricular block. Atrioventricular block and intraventricular block were both common in over fifth decade.
3. The abnormal ECG findings wjth first degree atrioventricular block were sinus bradycardia(27.3%), left ventricular hypertrophy(21.2%), atrial enlargement(12.2%). In third degree atrioventricular block, the majority(50.0%) showed atrioventricular junctional escape rhythm. In complete right bundle branch block, there were 22.8% of atrial fibrillation and 14.3% of myocardial infarction. In incomplete right bundle branch block, there were 29.4% of both atrial enlargement and atrial fibrillation. In left anterior hemi-block. there was 21.5% of sinus bradycardia.
