[Several factors leading to absolute arrythmia in acquired valve defects (preliminary report)]

Some of the most important factors leading to arrhythmia perpetua in acquired valvular diseases are discussed in the paper, with the analysis of the material from 96 patients (68 females and 28 males). A group of 98 patients (73 males and 25 females) with degenerative cardiovascular diseases was parallelly studied. The importance of the time of the onset of the first rheumatic attack is stressed upon as well as upon the number of recidivations upon the valvular defect type and upon the additional degenerative myocardial changes in the evolution of the valvular cardiopathy.
