[Ventricular preexcitation syndrome (Wolff-Parkinson-White syndrome)].
On the base of 25-year follow up on 88 subjects with Wolf-Parkinson-White syndrome the results obtained from the studies are reported -- a syndrome being found from the clinically and electrocardiologically examined patients: males 67.2 per cent and 31.8 per cent -- females. Clinically healthy were 32 (36.35%) and the following diseases of the cardiovascular system were detected with the dynamic follow up of the rest 56 subjects: 27.25 per cent rheumocarditis or rheumatic valvular disease, tonsillo-cardiac syndrome in 11.4 per cent, chronic ischemic heart disease in 12.5 per cent, heart infarction, acute stage -- in 3, hypertonic states -- in 6 and with congenital tricuspidal malformation of Ebstein and with thyreoto ic heart. The electrocardiographic characteristic showed type A in 37.5 per cent type B in 54.7 per cent and syndrome of Lown-Ganumg-Levin in 7.8 per cent. A transitory form of the syndrome was found in 11.4 per cent and in 6.8 per cent -- intermittent form. Paroxysmal tachycarida was found in 49 cases (55.8%), supraventricular form being the case in 39 of them, ventricular in 5 and on another 5 -- paroxysmal fibrillation -- tachycardia form. The concept is advanced that the presence of paranodal ectopic excitation centers with enhanced activity and functional lability of A-V node are of pathogenetic importance in the acquired forms of WPW syndrome.
