1. A leadless cardiac pacemaker (LCP) configured to sense cardiac activity and to pace a patient'"'"'s heart, the LCP comprising:
- a housing;
an electrode secured relative to the housing and exposed to an environment outside of the housing;
a gyroscope disposed relative to the housing;
circuitry in the housing in communication with the electrode and the gyroscope, the circuitry configured to generate a twisting profile over one or more cardiac cycles based at least in part on data obtained from the gyroscope;
wherein the circuitry is further configured to;
update one or more pacing parameters of the LCP based at least in part on the twisting profile; and
pace the patient'"'"'s heart with the electrode using one or more of the updated pacing parameters.

Abstract
An implantable medical device (IMD) that includes a housing, a first electrode secured relative to the housing, a second electrode secured relative to the housing, and a gyroscope secured relative to the housing. The IMD may include circuitry in the housing in communication with the first electrode, the second electrode, and the gyroscope. The circuitry may be configured to determine and store a plurality of torsion data measurements, from which a representation of a twist profile may be determined.

15. A method for monitoring cardiac dysfunction of a patient'"'"'s heart using a leadless cardiac pacemaker (LCP) secured to the patient'"'"'s heart, wherein the LCP includes a housing, an electrode secured relative to the housing and exposed to an environment outside of the housing, and a gyroscope disposed relative to the housing, comprising:
-
delivering a therapy to the patients'"'"' heart using the LCP; determining a twisting profile over one or more cardiac cycles based at least in part on data obtained from the gyroscope of the leadless cardiac pacemaker (LCP); adjusting one or more therapy parameters of a therapy for the patient'"'"'s heart based at least in part on the twisting profile; and delivering the adjusted therapy to the patient'"'"'s heart using the LCP. - View Dependent Claims (16, 17, 18, 19, 20)
