signal averaged electrocardiography

Cardiology A technique that amplifies late potentials–high-frequency, low-amplitude signals at the end of the QRS complex, attributed to fragmented and delayed conduction through the borders of a myocardial scar

The term "signal averaged electrocardiography" incorporates any technique in which multiple electric signals from the heart are averaged to improve the signal to noise ratio in order to reveal ventricular late potentials1.

Improved recognition of sustained ventricular tachycardia from SAECG by support vector machine

VLPs, as detected by signal averaged electrocardiography, act as non-invasive marker for the development of ventricular tachyarrhythmias.13 The criteria for their presence and their co-relation with ventricular tachyarrhythmias are now well established.10 In our study 9 out of 37 cases (24.32%) had ventricular late potentials on their signal averaged electrocardiography, whereas only 1 out of 37 controls (2.7%) had this abnormality.
