[Incidence and characteristics of cardiac rhythm disorders after myocardial infarct].
In the course of 1 year 130 patients were examined who had survived myocardial infarction and were alive 2 months after the onset of the disease and were included into the Myocardial Infarction Registry. After 2,3,6,9 and 12 months ECG of various duration was recorded. The prolongation of ECG recording permits to give a more precise characteristics of the incidence and nature of the rhythm disorders observed in chronic ischaemic heart disease patients. Repeated heart rhythm examinations at rest during 1 hour, or during physical exercises (bicycle test) permitted to reveal rhythm disorders in 72.2--66.7% of the patients, and among them ventricular extrasystole in 62.6--66.7% of those examined, respectively. The appearance of ventricular extrasystoles correlates with the state of the patients surviving myocardial infarction A higher incidence of ventricular extrasystoles is observed in pateints with distinct tecg changes, with angina pectoris and elevated blood pressure (larger than or equal to140/90mm Hg).
