title: [Electrovectorcardiographic characteristics of shifting repolarization phase curves in patients with hypertrophic cardiomyopathy and ischemic heart disease with arterial hypertension].
abstract: Possible electrovectorcardiographic approaches to the diagnosis of hypertrophic cardiomyopathy (HCMP) are considered on the basis of a study of 85 HCMP patients, 44 coronary patients with postinfarction cardiosclerosis and arterial hypertension (CD + AH), and 83 normal subjects. Particular attention was paid to cases where myocardial scary changes and left-ventricular hypertrophy were detected electrocardiographically as their interpretation was difficult because of similar changes in the QRS complex being typical for postinfarction cardiosclerosis. An analysis of quantitative and qualitative changes in the end segment of the QRS complex demonstrated a specific pattern of repolarization shift in patients with HCMP and CD + AH. The demonstrated changes can be useful in differential diagnosis of these conditions, facilitating the interpretation of infarction-like curves that are quite common in HCMP patients.
