Abstract
An implantable medical apparatus for detecting diastolic heart failure, DHF, has a DHF determining device for determining at least one blood pressure parameter for detecting a DHF state of the heart of a patient. The DHF determining device includes a pressure measuring unit for measuring pulse pressure in a cardiac cycle for a predetermined workload situation of the patient as the blood pressure parameter, and a comparator compares the measured pulse pressure with a predetermined reference value. A pacemaker includes such an apparatus and a control unit that optimizes pacing therapy depending on the result of the comparison of the measured pulse pressures with the predetermined reference values. A corresponding method of detecting diastolic heart failure, DHF, includes the step of determining at least one blood pressure parameter for detecting a DHF state of the heart of a patient by determining, as said blood pressure parameter, the pulse pressure in a cardiac cycle for a predetermined workload situation of the patient, and the determined pulse pressure is compared with a predetermined reference value.
