G.P. Verezhnikova. Electrocardiographic diagnosis of myocardial infarction combined with intraventricular conduction disorders

The article is devoted to the ECG diagnosis of myocardial infarction combined with disorders of intraventricular conduction. Myocardial infarction may occur against the background of existing intraventricular conduction disturbances, or be complicated by the emergence of acute intraventricular blockades. The article discusses ECG changes depending on the location of the disturbances in the system of Gis – Purkinje and focal myocardial lesions. We provide some ECG criteria of acute coronary syndrome combined with left bundle branch blockade, as one of the most difficult electrocardiographic syndromes.
