Vectorcardiography


vectorcardiography

[¦vek·tər‚kärd·ē′äg·rə·fē] (physiology) A method of recording the magnitude and direction of the instantaneous cardiac vectors.

Vectorcardiography

 

a method of spatial (volumetric) investigation of the electric field of the heart. It is one of the forms of electrocardiography. Vectorcardiography was proposed in 1913 by the Dutch scientist W. Einthoven.

vectorcardiography


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

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.

vec·tor·car·di·og·ra·phy

(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.
