In order to determine the real value of the amplitude variations of the R wave V5 during a stress test, in the recognition of coronary insufficiency, the stress tests of 227 patients were reviewed and compared to the results of coronary angiography. This permitted to find 93 patients with healthy coronaries and 134 patients presenting an involvement of the anterior inter-ventricular artery (AIVA); 37 have a one-vessel disease, 38 have a two-vessel disease, 59 a tri-vessel disease. Quantitative analysis of the modifications of the R wave in V5 during stress, finds mean values of amplitude variations of 1.

In mitral stenosis, short axis views enable a quantitative evaluation of mitral surface area by planimetry. Long axis views contain additional important information on the state of the subvalvular apparatus and on the possible presence of left atrial thrombosis.
