Abstract：Objective To investigate the relationship between hypoxia and induced arrhythmias .Methods 207 patients were collected as research objects for the retrospective study .According to the 24 h ECG monitoring , the patients with arrhythmia were taken as the observation group (n=55).Other patients without arrhythmia were collect-ed as the control group(n=152).Pulmonary function, blood gas, degree and time of hypoxia and the correlation be-tween the onset time and the frequency of hypoxia-induced arrhythmia were analyzed and compared between the two groups.Results There were no significant differences between the two groups in age , gender, BMI, smoking rate, pH, systolic pressure , diastolic pressure and basic heart disease constituent ratio ( P>0.05 ) .There was no signifi-cant difference between the two groups in cardiac functional grading distribution ( P>0.05 ) .FEV1%of the observa-tion group(78.4 ±3.2) was significantly lower than that of the control group (90.6 ±1.8), SpO2 value of the obser-vation group(0.84 ±0.06) was significantly lower than that of the control group (0.97 ±0.04 )(P<0.01).There were no significant differences in SpO 2 and arrhythmia occurrence frequency among the three subgroups of the obser-vation group who suffered from coronary heart disease , AMI and hypertension heart disease ( P>0.05 ) .There were significant differences in discrepancy between hypoxia and arrhythmia occurrence time among the different gruops ( P<0.05).There were significant negative correlations between arrhythmia occurrence frequency and SpO 2 value, FEV1%value in the observation group ( r=-0.376 , P<0.05; r=-0.331 , P<0.05 ) .Hypoxia had no signifi-cant correlation to the occurrent time of arrhythmia .Conclusion The patients with arrhythmia combined with basic heart diseases have lower SpO 2 , FEV1%value than the patients without arrhythmia have .There is a negative correla-tion between the frequency of arrhythrmia and SpO 2 value, FEV1%value.
