Figure 1From: Usefulness of the heart-rate variability complex for predicting cardiac mortality after acute myocardial infarction Receiver-operator characteristic curves for predicting cardiac deaths by HRV complex, 6 dimension, 8 dimension, LVEF, SDNN and DC. Sensitivity is determined from the proportion of cardiac deaths identified as high risk; specificity is determined from the proportion of survivors identified as low risk.Back to article page
