The functional state of the myocardium and pulmonary hemodynamics after the elimination of atrial fibrillation

The structure of ventricular systole and pulmonary rheogram in atrial fibrillation and after restoration of sinus rhythm were studied in 49 patients. Atrial fibrillation is accompanied by a decrease in myocardial contractile function and pulmonary hypertension. After the reversion of the sinus rhythm, the phase shifts of the systole structure and the symptoms of pulmonary hypertension significantly decreased, some of the indicators returned to normal. The best results were achieved with the use of electro-impulse therapy, which makes it possible to consider this method more beneficial in comparison with quinidine therapy.
