[Intraventricular blocks in myocardial infarct].
The examination was carried out in 787 patients with macrofocal myocardial infarction. The most frequently encountered variant of intraventricular block in males was the right bundle branch block, in females--the left bundle branch block. The rarest variant of intraventricular conductivity disorders in myocardial infarction was the left-posterior hemiblock. The prognostically severest variant of bilateral block consists in a combination of the right bundle branch block with the left-posterior hemiblock. The leading causes of death among the patients with myocardial infarction and intraventricular blocks were acute (cardiogenic shock, pulmonary oedema) and chronic cardiac insufficiency. In patients with bilateral blocks the frequent causes of death were, along with cardiac insufficiency, also arrhythmias (ventricular fibrillation, asystole).
