[Myocardial infarction-related arrhythmia after rehabilitation treatment in a sanatorium].

The study involved 100 patients (80 men and 20 women), aged between 27 and 69 years treated at the Department of Cardiology, Medical Academy in Lublin for the first myocardial infarction, and classified for a 4-week rehabilitation in sanatorium. A 24-hours ECG recording with Holter technique (Medilog 3000 manufactured by Oxford Medilog Timed) was performed twice. In the first record cardiac arrhythmias ( extrasystole both supra- and ventricular, ventricular tachycardia) were more frequent in comparison with the results of the second recording carried out after a 4-week rehabilitation.
