Figure 3 Dependence of mortality during EMIAT follow-up on the cut-off values of depressed HRV. For each HRV value, the graphs show the mortality in patients with HRV measure the value on the horizontal axis (that is, when using the value on the horizontal axis as a dichotomy cut-off). Open areas = noncardiac mortality; grey areas = cardiac nonarrhythmic mortality; solid areas = arrhythmic mortality. HRV = heart rate variability.
