Analysis of human atrial fibrillatory waves using monophasic action potential technique

Abstract In 29 patients with atrial fibrillation, using the monophasic action potential technique, the fibrillatory waves were recorded and analyzed by statistical methods. Concerning the characteristics of the fibrillatory waves there are no differences between patients with rheumatic heart disease and with coronary heart disease. The patients with paroxysmal forms and those without heart failure and with normal heart size, have similar statistical data with regard to their fibrillatory waves. From the data presented, it could be possible to predict the efficacy of conversion to sinus rhythm and also the sinus rhythm stability after conversion.
