Implantable Medical Device for Sensing Electrocardiogram Signals

Abstract

An implantable medical device for sensing electrocardiogram signals includes an arrangement of electrode poles configured to sense electrocardiogram signals, and a processing module for processing electrocardiogram signals received via said arrangement of electrode poles. The processing module is configured to switch between a first mode of operation and a second mode of operation. The processing module, in said first mode of operation, is configured to identify a predefined event based on sensed electrocardiogram signals and to record a snapshot signal representation of electrocardiogram signals over a first duration of time. The processing module, in said second mode of operation, further is configured to record a continuous signal representation of electrocardiogram signals over a second duration of time larger than said first duration of time.

Dependencies are inferred from the claim text.
