The Q-T Interval in Rheumatic Fever
In 143 rheumatic children the Q-T interval was found to be normal in those with quiescent rheumatic heart disease. In 29 with fatal pancarditis the average Q-T was above the average normal, though not beyond the upper limit of normal. Although parallel changes in the Q-T interval and the clinical manifestations of rheumatic fever occurred in about 66 to 75 per cent of cases, there were significant number of instances where changes in the Q-T and in the clinical course of the disease were in opposite directions.
