title: [Diagnostic value of bloodless graphic methods of studying the heart and vessels in the early detection of circulatory insufficiency].
abstract: Based on the experience gained in examining over 3000 patients with various cardiovascular diseases (hypertensive, ischemic heart disease, myocarditis, heart failures of different etiology, etc) and upon literature sources a clinical grouping of bloodless methods of exploring the heart and vessels is given. At the root of the grouping is laid an investigation into the parameters of the cardio-vascular activity. Attention is called to widely employed and well-approved methods, such as electrocardiography, echocardiography and to the ones holding good promise (magnitocardiography, contactless investigations of the arterio-venous pulsation, etc). The authors believe the most informative bloodless methods of examination to be the ones that reflect the parameters of the cardio-vascular activity in a direct way, whereas methods reposing on the study of secondary manifestations produced by the work of the heart and vascular system (ballisto-, dynamo-, cardiovectorography and others) appear to them less promising with their significance for the clinical practice being of minor importance. The "bloody" and bloodless graphic methods of examining the heart and vessels do not compete with each other, but are mutually complementary. The diagnostic merit of the methods in recognizing circulatory insufficiency increases by using functional load and pharmacological tests.
