Abstract：ObjectiveTo investigate the relationship between abnormal electrocardiogram （ECG）and sleep apnea hypoventilation syndrome（SAHS）by analyzing the ECG results between SAHS and nonSAHS patients. MethodsAll patients were divided into two groups: 388 patients with SAHS and 388 patients without SAHS. The ECG changes of two groups patients were compared and analyzed. Results There were significant differences in incidence of atrial premature，atrial fibrillation，bundle branch block，atrioventricular block between two groups (P＜0.05)；There were significant differences in incidence of ventricular premature，ST-T changes (P＜0.01). ConclusionVariety of abnormal ECG changes can be caused by SAHS，mechanisms associated with hypoxemia by apnea.
