Abstract

The signal-averaged ECG is an accepted tool for the identification of patients prone to malignant arrhythmias. There have been several reports of risk assessment using the magnetocardiogram (SA-MCG) [2, 3, 5]. Reports of time-domain analysis of the signal-averaged QRS complex in the MCG using the Simson criteria [4], especially the filtered QRS duration, have been inconsistent as to the correlation of MCG values and predictive accuracy to the SA-ECG [2, 3, 5]. We investigated the correlation of the time-domain analysis of signal-averaged multichannel MCG recordings to the signal-averaged ECG.
