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

摘要

This retrospective study assesses the feasibility of using an 80-lead body surface map (BSM) rather than the conventional 12-lead electrocardiogram (ECG) with exercise stress echocardiograms A total of 122 patients comprised an 80-lead BSM group (n = 50) and a 12-lead ECG group (n = 72) Both groups had comparable mean maximum predicted heart rates (PHR) and image acquisition periods (P for both groups was < 0001) However, image acquisition in the 80-lead group had a time lapse twice the duration than the 12-lead group (P < 0001), As a result of this delay, images acquired in the 80-lead group occurred below the required 85% PHR and was 8% lower in heart rate than the 12-lead group (P <- ,0001) Although the 80-lead BSM has diagnostic potential, it causes significant delay of the acquisition process postexercise and could impair the diagnostic utility of exercise echocardiography.
