[Sinoatrial block with Wenckebach's period: diagnosis by means of automatic analysis of the cardial rhythm structure and clinical evaluation]

Computer served to study by automatic analysis the structure of the cardiac rhythm in 190 patients: 123 patients after removal of the persistent form of atrial fibrillation, 24 with neuro-circulatory dystonia and 43 healthy individuals. Sino-atrial block with Samoilov-Wenkebach periods was recorded in 26 individuals. The characteristic changes of the cardiointervalogram in the given disorder of intracardiac conduction are described, which facilitates diagnosis considerably. The sino-atrial block with Samoilov-Wenkebach periods in the observed was not accompanied by clinical symptoms and exerted no untoward effects on the distant results of electro-impulse therapy in patients with persistent forms of atrial fibrillation.
