MEASURES OF CARDIAC CONRACTILITY VARIABILITY DURING ISCHEMIA

摘要

Systems and methods include obtaining a measure of cardiac contractility. A cardiac contractility variability (CCV) is determined from the measure of cardiac contractility. Analyzing the cardiac contractility variability, an indication of cardio-vasculature health is provided. In an example, the CCV can be determined using variability metrics of RR interval or Sl amplitude.
