[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.

[Detection of heart rhythm disorders by ECG autotransmission via telephone].

The method of patient's own telephone transmission of his or her ECG was used for the diagnosis of arrhythmias in 70 patients with a history of heart rhythm disorders. Various arrhythmias were diagnosed, using this method, in 91.4% of the patients. Repeated conventional ECG recordings detected arrhythmias in 54.3% of the patients only over the entire hospital stay time. A comparison of ECG telephone autotransmission and intermittent ECG tape-recording by the Cardiocassette device showed identical rhythm disorders in 91.3% of the cases, while bicycle ergometry proved less informative for the diagnosis of arrhythmias as compared to ECG telephone transmission. The latter method may be useful in monitoring patients with heart rhythm disorders, particularly at the outpatient stage of treatment. It allows antiarrhythmic therapy to be administered as soon as arrhythmia is detected which is an advantage over ECG tape-recording.

[Prevention of ventricular fibrillation in animal experiments].

The precursors of ventricular fibrillation and asystole developing after ligation of a branch of the coronary artery and adrenalin injection were studied in 30 albino rats. The comparative efficacy of antiarrhythmic agents (ajmalin, lidocaine, isoptin, visken) in the prevention of ventricular fibrillation induced by electric current was determined in 40 rats. Ventricular extrasystole and tachysystole as well as the block of the bundle of His branch were the most common precursors of ventricular fibrillation. In some experiments fibrillation was preceded by complete atrioventricular block, cardiac fibrillation, sinus bradycardia, nonparoxysmal ventricular tachycardia, and excaped ventricular contractions. Ventricular asystole was most frequently preceded by complete atrioventricular block and the bundle of His branch block. Among the antiarrhythmic agents studied, ajmalin proved most effective in prevention of ventricular fibrillation; it raised the fibrillation threshold in all animals. Lidocaine, which produced a prophylactic effect in 50% of experiments, was second in effectiveness. Changes in the ventricular fibrillation threshold due to the effect of these agents were statistically significant on the average. Isoptin and visken proved to be less effective.
