Submaximum bicycle and respiration ergometry was conducted before and after sinus rhythm recovery by means of electric impulse stimulation in 41 patients with atrial fibrillation after effective mitral commissurotomy. Physical working capacity was reduced considerably (by 25.8%), while oxygen spending per unit of work increased by 58.5% in patients with atrial fibrillations, as compared to normal subjects. After sinus rhythm was recovered, physical working capacity increased by 106%, while oxygen spending per 1 kgm work declined by 34.2%. Sinus rhythm recovery is essential as an element of postoperative rehabilitation in cardiosurgical patients. |
