Abstract
An implantable vagus nerve stimulation (VNS) system includes a sensor configured to measure ECG data for a patient, a stimulation subsystem configured to deliver VNS to the patient, and a control system configured to perform a heart rate variability analysis with the ECG data. In some aspects, performing the heart rate variability analysis includes measuring R-R intervals between successive R-waves for the ECG data measured during a stimulation period of VNS therapy and a baseline period of the VNS therapy, wherein the stimulation period comprises at least a portion of the ON period and the baseline period comprises at least a portion of the OFF period immediately preceding the ON period, and generating a plot of each R-R interval against an immediately successive R-R interval for each of the stimulation period and the baseline period configured to be displayed on a display.
