[Electro- and phonocardiographic changes in tonsillogenic cardiopathies and primary rheumocarditis].

With the use of computers it proved possible to distinguish the most informative electro- and phonocardiographic signs in variants of tonsillogenic affection of the heart and primary rheumatic carditis as the result of which the severity of the myocardial affection could be judged. These signs are very important in the choice of the treatment and in prognosis. Cardiac-type neurocirculatory dystonias are characterized by the fewest informative signs indicative of vegetative effects produced on the heart. In tonsillogenic myocardial dystrophy, the number of informative signs and their pronounced character increase, which is evidence of more complex disorders in the heart. The signs in infectious-allergic myocarditis and primary rheumatic carditis are common in character, which makes differential diagnosis difficult and calls for further research into new diagnostic methods. According to the phonocardiogram, a systolic murmur was present in patients of all the groups that were examined, which had specific features in neurocirculatory dystonia and in tonsillogenic myocardial dystrophy. No essential differences were found in myocarditides.
