title: [Apex cardiography in the assessment of the signs of early disorder of myocardial contractile capacity].
abstract: Asynergia of systolic wave of the apexcardiogram was studied in 54 patients with various forms of ischemic heart disease. The paradoxical protrusions were divided into 4 types. A directly proportionate dependence was disclosed between the magnitude of asynergy and the degree of the pathological condition. The paradoxical protrusion diminished during treatment and rehabilitation in most patients, in some it disappeared, which may point to the functional character of disorders of myocardial contractility.
