Detection and/or monitoring of diastolic heart failure
First Claim
1. An implantable medical device for detecting and/or monitoring progression of diastolic heart failure DHF of a patient, comprising a first measurement unit that measures in vivo a parameter indicative of left ventricular ejection fraction LVEF, an implantable second measurement unit that measures in vivo a variable indicative of the workload of the patient, an implantable determination unit that determines a relation between LVEF and the workload of the patient, and an implantable DHF unit that detects DHF and/or monitors progression of DHF from said relation.

Abstract
In an implantable medical device for detecting and/or monitoring the progression of diastolic heart failure (DHF), and a corresponding method, a parameter is measured that is indicative of left ventricular ejection fraction (LVEF), and a variable is also measured that is indicative of the workload of the patient, and a relation is determined between LVEF and the workload, and DHF is detected and/or the progression of DHF is monitored, dependent on this relation.
