Comparative Analysis Using the 80-Lead Body Surface Map and 12-Lead ECG With Exercise Stress Echocardiograms

Abstract

This retrospective study constituted of 144 patients who were recruited at the University of California Davis Medical Center (UCDMC) Echo and Stress Laboratory during a 10-month period by referrals for standard ESE to assess for CAD. Participation criteria included referral for a standard ESE, age older than 18 years, and the same criteria as standard stress tests. Standard stress test exclusion criteria were applied as well (Table 1).12 All patients gave informed consent. The study group, called the 80-lead BSM group, consisted of 72 participants. Seventy-two random participants comprised the 12lead ECG group (see Table 2). Twenty-two participants in the 80-lead group had poor image quality ESE or incomplete data for exercise cessation and/or image acquisition real time; as a result, these participants were excluded from the study. None of the ESE of the 12-lead ECG group was considered of poor image quality, nor were any data incomplete. STRESS ECHOCARDIOGRAMS
