Univariate logistic regression for time and frequency domain heart rate variability measurements and sudden death status at five years
| Measurement | Odds ratio for sudden death for every 10% decrease in variable (95% CI) | p Value |
|---|---|---|
| CI, confidence interval; SDNN, standard deviation of all NN intervals. | ||
| SDNN (ms) | 0.95 (0.88 to 1.02) | 0.15 |
| Very low frequency power (ms2) | 1.01 (0.95 to 1.08) | 0.63 |
| Low frequency power (ms2) | 0.96 (0.78 to 1.19) | 0.74 |
| High frequency power (ms2) | 0.98 (0.84 to 1.14) | 0.84 |
| Total power (ms2) | 1.00 (0.95 to 1.05) | 0.80 |
