vectorcardiography

 [vek″tor-kahr″de-og´rah-fe]
the registration, usually by formation of a loop on an oscilloscope, of the direction and magnitude (vector) of the moment-to-moment electromotive forces of the heart during one complete cycle. adj., adj vectorcardiograph´ic.

vec·tor·car·di·og·ra·phy

(vek'tŏr-kar'dē-og'ră-fē),
The integration of scalar electrocardiographic recordings on two or three planes to produce a vectorcardiogram consisting of loops divided by a timing mechanism for all the waves of the electrocardiogram.

vectorcardiography

[-kär′dē·og′rəfē]
Etymology: L, vector, carrier; Gk, kardia, heart, graphein, to record
a method of recording the direction and magnitude of the heart's electric activity.

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.

(vek'tŏr-kahr'dē-og'ră-fē)
1. A variant of electrocardiography in which the heart's activation currents are represented by vector loops.
2. The study and interpretation of vectorcardiograms.
