Table 2
Characteristics of dynamic electrocardiograms of patients during sleep time and nonsleep time.
| Groups | Number of long R-R intervals (n = 48,840) | Average ventricular rate (times/min) | Slowest ventricular rate (times/min) | Fastest ventricular rate (times/min) |
| Sleep time | 12053 (24.68%) | 82.56 ± 6.89 | 41.46 ± 6.47 | 155.52 ± 12.26 | Nonsleep time | 36787 (75.32%) | 70.24 ± 8.51 | 35.51 ± 5.89 | 131.48 ± 10.87 | χ2/t | 250.50.012 | 22.475 | 4.809 | 29.307 | | <0.001 | <0.001 | <0.001 | <0.001 |
