A comparison of three methods of detecting ventricular incoordination in man, and the relation of their results to the amount of coronary arteriosclerosis.

The results secured by three tests for cardiac incoordination have been compared in over 100 cardiac cases. The Bcg found the abnormality more frequently than did Vgm and PDmax, the probable reasons for this are discussed. The cases in which cardiac incoordination was detected showed, on the average, more coronary arteriosclerosis than those whose hearts beat normally.
