Abstract:
Objective To investigate the relationship between obstructive sleep apnea hypopnea syndrome(OSAHS) and cardiac arrhythmia. Methods 160 snorers were recruited to undergo more than 7 hours nocturnal polysomnography(PSG) and 24 hours ECG monitoring, and were divided into OSAHS group (n=98) and control group (n=62) based on the results of PSG monitoring. Results There were significant differences in sleep apnea hypopnea index(AHI), SpO_2 and cardiac arrhythmia frequency between the OSAHS and control groups. Accompanying with the breath pause, SpO_2 decreased, and heart rate was periodic changes. The frequency of cardiac arrhythmia obviously increased when SpO_2 was lower than 80%. Conclusion During sleep the low oxygen saturations and fluctuation of autonomic nervous system play important roles in the cardiac arrhythmia in OSAHS patients.
