AUTOMATED LAPLACIAN ECG MOMENT OF ACTIVATION DETERMINATION ALGORITHM DURING PACING

摘要

ECG (LECG) is a unique technique for detecting cardiac electrical activity. The recurrent property of ECG is exploited by this unique algorithm for the detection of the QRS complexes by cross (auto) correlation. Further, the algorithm calculates the time offset of the LECG signal from the ECG peak. This offset is termed the moment of activation (MoA) and is determined automatically. LECG body surface isochronal maps depict information about cardiac activation patterns. Besio related the ECG QRS complex to the LECG isochrones by mapping the body surface MoAs. This unique automated algorithm during pacing, detected QRS complexes correctly 99.3% and mapped isochrones.
