1. A system comprising:
- an implantable medical device (IMD), the IMD including;
a detector configured to detect tachyarrhythmia;
a baroreflex detector to obtain baroreflex information associated with tachyarrhythmia, wherein the baroreflex detector includes a baroreflex sensitivity (BRS) indicator module configured to establish an indicator of the sensitivity of baroreflex of a subject using the baroreflex information, wherein the baroreflex information includes at least one of;
a measure of blood pressure measured synchronously with an artificially induced at least one of cardiac or respiratory perturbation, a measure of heart rate turbulence (HRT), and a measure of heart rate variability (HRV); and
a processor in communication with the tachyarrhythmia detector and the baroreflex detector, the processor configured to adjust at least one of a tachyarrhythmia detection parameter of the IMD or a tachyarrhythmia therapy parameter of the IMD using the BRS indicator.

Abstract
A system comprising an implantable medical device (IMD) that includes a tachyarrhythmia detector, a baroreflex detector to obtain baroreflex information, and a processor in communication with the tachyarrhythmia detector and the baroreflex detector. The processor adjusts at least one of a tachyarrhythmia detection parameter of the IMD or a tachyarrhythmia therapy parameter of the IMD using the baroreflex information.
