ELECTROMECHANICAL ACTIVATION TIME VIA HEMOTAG AND 2D ECHOCARDIOGRAPHY: CORRELATION WITH TRICUSPID REGURGITATION PEAK VELOCITY AND IMPLICATIONS FOR DIAGNOSIS AND CLINICAL PRACTICE

Background: Cardiac time intervals (CTI) have been classically obtained with phonocardiography, though this technique has been overlooked since the advent of the 2D M-mode echocardiography. The “HemoTag” is a new technology that uses heart sounds and an ECG signal transduced via 3 thoracic
