First Claim
Patent Images
1. An implantable medical device comprising:
- a data collection module configured to obtain a pressure signal;
a data processing module coupled to the data collection module,the data processing module configured to determine a pressure rate of change based on the pressure signal;
the data processing module configured to identify at least one of impaired relaxation and impaired contractility based on a maximum value of the pressure rate of change in order to detect ischemia; and
a therapy module coupled to the data processing module, the therapy module configured to at least one of deliver therapy and generate an alert when the at least one of impaired relaxation and impaired contractility is identified.
