CARDIAC RISK STRATIFICATION UTILIZING BAROREFLEX SENSITIVITY MEASUREMENT
First Claim
1. A method comprising:
- obtaining a baroreflex sensitivity (BRS) measurement for a patient via an implantable medical device (IMD); and
generating a risk stratification indicator based on the BRS measurement, wherein the risk stratification indicator classifies the patient into one of a plurality of cardiac arrhythmia or cardiac mortality risk categories.

Abstract
A monitoring or therapy system may obtain a baroreflex sensitivity (BRS) measurement via an implantable medical device (IMD). The monitoring or therapy system then may generate a risk stratification indicator based on the BRS measurement. In some examples, the IMD generates the risk stratification indicator, while in other examples, an external computing device, such as a programmer, generates the risk stratification indicator. The monitoring or therapy system also may obtain at least one of a heart rate variability (HRV) measurement and a non-sustained ventricular tachycardia (NSVT) indicator via the IMD, and may generate the risk stratification indicator based on the BRS measurement and one or both of the HRV measurement and the NSVT indicator. In some examples, the monitoring or therapy system may generate an instruction, indicator, or alert based on the risk stratification indicator. The indicator may indicate that the patient is a candidate for an implantable therapy device.
