In the MI focus, an ischemic zone is formed, which is characterized by a change in the repolarization process (T wave), an injury zone manifested by a displacement of the ST segment and a necrosis zone, which is expressed in a change in the QRS complex.</p></abstract><trans-abstract xml:lang="ru"><p>До настоящего времени в диагностике инфаркта миокарда (ИМ) основное значение придают ЭКГ-исследованиям.
