Text: (2) Incidence of Sinus bradycardia, sinus tachycardia, sinus arrest, atrial premature beats, ventricular premature beats, paroxysmal atrial tachycardia, paroxysmal ventricular tachycardia, atrial fibrillation, II-III degree atrioventricular block, ST-T segment changes were reduced from 57. 4 %, 44. 4 %, 7. 4 %, 20. 4 %, 13. 0 %, 36. 5 %, 12. 0 %, 8. 3 %, 37. 0 %, 53. 7 % to 4. 6 %, 1. 9 %, 0. 0 %, 3. 7 %, 2. 8 %, 7. 0 %, 0. 9 %, 0. 0 %, 1. 9 %, 4. 6 % (all P < 0. 05) and the total number of arrhythmias happened at night were significantly lower (all P < 0. 05) while the heart rate variability (HRV) were significantly higher (P < 0. 01) in NPPV group than in control group ; AHI was positively while LSaO2 was negatively correlated with the total night arrhythmia number (P < 0. 01).
