Abstract

The present invention relates to an implantable medical system for stimulating a patient's heart, comprising a memory unit (270), a processor (28), a stimulation unit (290) configured to stimulate the heart, and a detection unit (260) configured to detect a cardiac electric signal (250). The memory unit (270) stores a parameter allocation model which comprises a plurality of key sets (310, 420), each of which comprises a potential time of occurrence of at least one first event (110) in the cardiac electric signal (250) and each of which is mapped to at least one potential time of occurrence of a second event (130) in the cardiac electric signal (250) representing a repolarization of the myocardium. The memory unit (270) further stores a computer-readable read-out program that causes the processor (28) to perform the following steps when executed on the processor (28):- receiving a cardiac electric signal (250) comprising a plurality of events (110),- for at least one first event (110) in the received cardiac electric signal (250), determining an actual time of occurrence,- finding the key set in the list of key sets of the parameter allocation model that is closest to the actual time of occurrence, and- retrieving an estimation time from the parameter allocation model, which represents an estimation of the time of occurrence of the second event (130), based on the at least one potential time of occurrence of the at least one second event (130) to which the closest key set is mapped.
