ABSTRACT:
This invention provides an improved Holter function in an implantable device for arrhythrnia monitoring or therapy. One improvement consists of a zoom feature which stores information about an arrhythmia episode at several levels of detail, with increasing levels of detail corresponding to shorter recording periods, and with a way to display the relation in time of the recordings at different levels of detail. The invention also introduces a novel implantable Holter function called an event log, which records time-stamped events once each minute, on changes in detected rhythm, or on application of antiarrhythmia therapy. The invention also provides logic for arbitrating which arrhythmia episodes the device saves in its memory.
