vectorcardiography


vectorcardiography
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.
- spatial v. three-dimensional v. in which vector loops are inscribed in frontal, sagittal, and horizontal planes.
