Left Ventricular Electromechanical Mapping

**Semantic type:** Diagnostic Procedure

**Definition:** A diagnostic tool that can be used to identify viable myocardium. It uses an ultra-low, magnetic-field energy source and a location sensor-tipped electrode catheter to construct electrical and mechanical maps of the left ventricle (LV) in three dimensions.
