Active medical device including means for reconstructing a surface electrocardiogram using far-field signals taken from an intracardiac electrogram

摘要

The device has an acquiring unit acquiring ventricular intracardiac electrogram signal and auricular intracardiac electrogram signal. An extracting unit extracts ventricular farfield component from the acquired ventricular intracardiac electrogram signal and auricular intracardiac electrogram signal. An auricular farfield estimator filter (18) receives auricular farfield component as input and delivers filtered auricular farfield signal as output. An adding unit (20) adds the filtered auricular and ventricular farfield signal for delivering electrocardiography signal as output.
