[Study of the dynamics of cardiac rhythm and the ST segment in patients with acute myocardial infarction based on the data of Holter ECG monitoring].
Holter monitoring was performed on days 1-2, 6-9 of the disease and on days 30-60 before their discharge from hospital in 54 patients with acute gross myocardial infarction. The presence of cardiac rhythm and conduction disturbances and ischemic ST-segment depression or elevation was evaluated. The patients having frequent and prolonged (more than 3 hours during a 2-day follow-up) showed a complicated course of the disease: recurrent pain syndrome, signs of heart failure, prolonged cardiac arrhythmias, and fatal outcomes. The patients with uncomplicated acute myocardial infarction had no long-term episodes of ischemic ST-segment depression or elevation, as recorded by Holter monitoring in the first 2 days of the disease. On days 6-9 no cardiac rhythm and conduction disturbances that had been observed in them were recorded. The patients in whom the episodes of silent myocardial infarction remained on their discharge exhibited a high (35%) incidence of myocardial infarction recurrence within a year.
