Abstract:
Objective:To determine the relationship between nocturnal oxygen desaturation and ventricular ectopy and study the effect of sleep stages on the frequency of ventricular ectopy in patients with chronic obstructive pulmonary disease (COPD).Method:Twenty two clinically stable patients with mild moderate COPD underwent overnight polysomnography,arterial oxygen saturation (SaO2) and ECG were recorded simultaneously.The relationship between the frequency of ventricular ectopy (VE) and SaO2,sleep stages and compared the results with those of twelve normal control subjects.Result:The prevalence of nocturnal VE in patients with COPD was 59.1 percent which was obviously higher than that of control group.The frequency of VE had no correlation with the frequency and the degree of oxygen desaturation,the duration of SaO2 below 90 percent,nocturnal mean SaO2 and nadir SaO2.The frequency of nocturnal VE during wake stage,REM stage and NREM stage had no difference.Conclusion:These results suggest that mild moderate nocturnal oxygen desaturation and sleep stages had no apparently influence on the events of VE in stable patients with COPD.
