Determination of reference annotation time from multi-channel electro-cardiogram signals

摘要

A method includes receiving a plurality of mapping electro-cardiogram (ECG) signals from respective mapping electrodes coupled to a surface of a heart of a patient. Multiple reference ECG signals are received from respective reference electrodes coupled to the patient. The multiple reference ECG signals are jointly processed, so as to produce a single timing reference indicative of cardiac cycle timing of the heart. The single timing reference is applied to the mapping ECG signals.

1. A method, comprising:
receiving a plurality of mapping electro-cardiogram (ECG) signals from respective mapping electrodes coupled to a surface of a heart of a patient; receiving multiple reference ECG signals from respective reference electrodes coupled to the patient; jointly processing the multiple reference ECG signals by selecting from among the reference ECG signals two or more preferable ECG signals that meet a signal quality criterion, and deriving the single timing reference from the selected preferable ECG signals, so as to produce a single timing reference indicative of cardiac cycle timing of the heart; and applying the single timing reference to the mapping ECG signals.
