[The structural-functional status of the myocardium and the electrophysiological indices in patients with atrial fibrillation].
A study is presented of 100 male patients with paroxysmal forms of atrial fibrillation (age: from 16 to 66 years). It is concluded that the determinant substrate of formation of atrial fibrillation is not limited to functional, electrophysiologic and morphologic state of the atria but encompasses the entire conduction system and structure of the myocardium both on the atrial and ventricular level. The frequency of paroxysms of atrial fibrillation and their severity are in direct dependence not only on the electrophysiological values but also on the degree of structural changes of the myocardium.
