signal-average electrocardiogram (SAECG)

an electrocardiographic study, usually performed on patients with unexplained loss of consciousness or suspected arrhythmias, in which hundreds of QRS complexes are collected, filtered, and analyzed to discover the presence or absence of certain abnormalities in the conducting system of the ventricle.

SAECGs were acquired using modified-XYZ Frank orthogonal leads and QRS-triggered coherent-averaged up to the noise level of 0.
The ACC document (1) also stated that SAECG had value in identifying patients with ischemic heart disease and unexplained syncope who are likely to have inducible SVT (sVT+).
The Agency for Health Care Policy and Research (2) published a Health Technology Assessment of SAECG, concluding that clinical studies of SAECG consistently demonstrated a very high negative predictive value (76-100%), variable sensitivity (35-83%) and specificity (47-91%), and poor positive predictive value (8-48%) when performed in patients with cardiomyopathy or following MI.
ART's participation, in accordance with the Research Agreement, will be to provide hardware (ART 1200 EPX) and software - including the Windows(R) based Predictor(R) SAECG analysis - to support the signal averaged ECG aspect of this study.
The inclusion of ART's proprietary SAECG technology products in this study as one of the clinical variables to stratify the risk of arrhythmias and sudden cardiac death for the purpose of identifying patients with increased benefit from implantable cardiac defibrillator therapy is a significant event for the Company.
