ECG changes in 1000 patients were studied, 950 with rheumatic disease attack and 150 controls with other diseases. The phenomenon of increase dynamics in AV conduction is established in 67% of ECG in the group of rheumatic patients with attacks, characterizied by inverse non-physiological correlations between heart frequency and atrioventricular conduction. With heart frequency acceleration--AV conduction time (PQ) is lengthened and vice versa--in slowing down of heart frequency--the conduction time PQ is shortened. In the control groups its frequency ranges between 3 to 8%. In healthy individuals and vegetoneurosis it can be isolated met. That inverse dynamics of AV conduction marks the pathophysiological and electrophysiological changes in myocardium in rheumatism and is of high diagnostic value. |
