Comparison of mean (SE) heart rate and heart rate variability (HRV) measurements according to the presence or absence of known cardiovascular disease (CVD)
| Variable | Non-CVD | CVD | Prior MI | Current CHF |
|---|---|---|---|---|
| Heart rate is mean resting heart rate at time of HRV measurement. | ||||
| Resting heart rate(beats/min) | 72 (10) | 72 (12) | 70 (9) | 75 (8) |
| ln LF-HRV (ms2) | 5.0 (1.2) | 4.2 (1.3) | 4.6 (1.3) | 3.8 (1.7) |
| ln HF-HRV (ms2) | 5.6 (1.1) | 5.0 (1.2) | 5.1 (1.2) | 4.9 (1.2) |
| ln RMSSD (ms) | 3.7 (0.3) | 3.7 (0.4) | 3.7 (0.5) | 3.6 (0.4) |
| ln SDNN (ms) | 4.0 (0.3) | 3.9 (0.4) | 4.1 (0.3) | 3.8 (0.4) |
