vectorcardiography

Spatial electrocardiography, 3-D electrocardiography Cardiology A sophisticated type of EKG, which simultaneously demonstrates myocardial activity and damage; in VC, the strength and direction of electric currents passing through the heart are represented as vector loops Application Diagnose and monitor left-sided hypertrophy and hyperfunction, bundle branch blocks and MIs; VC informs on the direction of heart muscle activity as well as its force vis-a´-vis contraction and relaxation.
