AN IMPLANTABLE ATRIAL DEFIBRILLATOR AND SYSTEM HAVING MULTIPLE CHANNEL ELECTROGRAM TELEMETRY AND METHOD

摘要

A defibrillator system includes an implantable defibrillator and a non-implantable external receiver. The implantable defibrillator includes a first sense channel for generating a first electrogram and a second sense channel for generating a second electrogram. The defibrillator further includes a cardioverter for applying cardioverting electrical energy to the heart and a transmitter for transmitting the first and second electrograms. The non-implantable receiver includes a display for simultaneously displaying the first and second electrograms. The implantable defibrillator may further include an event detector having a threshold for detecting cardiac events in one of the electrograms and an event marker generator for generating an event marker for each detected cardiac event. The transmitter transmits the event detection markers and the display displays the event detection markers and the thresholds with the corresponding electrogram.
