vectorcardiogram

 (VCG) [vek″tor-kahr´de-o-gram″]
a graphic representation of the magnitude and direction of the action currents of the heart, in the form of a vector loop. See also vectorcardiography.

vec·tor·car·di·o·gram

(vek'tŏr-kar'dē-ō-gram),
A graphic representation of the instant-to-instant magnitude and direction of the heart's action currents in the form of vector loops.

/vec·tor·car·dio·gram/ (VCG) (vek″ter-kahr´de-o-gram″) the record, usually a photograph, of the loop formed on the oscilloscope in vectorcardiography.

vectorcardiogram

[-kär′dē·əgram′]
Etymology: L, vector, carrier; Gk, kardia, heart, gramma, record
a tracing of the direction and magnitude of the heart's electrical activity during a cardiac cycle. It is produced by an oscilloscope, which simultaneously records three standard leads.

The Vectraplex Holter System is an ambulatory cardiac monitor that patients can wear at home or in the hospital to detect ECG changes suggestive of an AMI within seconds and derive the 15 lead ECG (12 lead and vectorcardiogram XYZ leads, including VCG loops) from the acquisition of only 3 leads (5 electrodes).

It was able to restore the vectorcardiograms, basing only on the cardioelectric potentials distribution on the body surface, without using the network (2, 3).
I'd do the vectorcardiograms and the echocardiograms and look at the series of x-rays.
