System and Method for Identifying a Cardiac Arrhythmia Event Following a Myocardial Infarction

A system for identifying a cardiac arrhythmia event in a patient the system comprising:

• an implantable medical device for sensing electrocardiogram signals, the implantable medical device comprising an arrangement of electrode poles configured to sense electrocardiogram signals;
• and
• a processing arrangement for processing electrocardiogram signals obtained by the implantable medical device;
• wherein the processing arrangement is configured to
• use a first setting of at least one detection parameter for detecting a cardiac arrhythmia event based on said electrocardiogram signals,
• obtain information indicative of a myocardial infarction event and
• in response to obtaining said information, adapt said at least one detection parameter to a second setting different than the first setting for detecting a cardiac arrhythmia event in a time period subsequent to obtaining said information indicative of a myocardial infarction event.
