Blood Pressure and Heart Rate Coefficients of Variability
| Variables | Mean | SD |
|---|---|---|
| CV-SBP awake | 0.088 | 0.02 |
| CV-SBP asleep | 0.088 | 0.03 |
| CV-DBP awake | 0.15 | 0.05 |
| CV-DBP asleep | 0.14 | 0.05 |
| CV-HR awake | 0.14 | 0.04 |
| CV-HR asleep | 0.12 | 0.06 |
CV = coefficient of variation
Calculation of CV: CV = standard deviation of parameter by mean; i.e, CV-SBP awake = awake SBP standard deviation in mmHg/awake SBP mean in mmHg
