The effect of digitalis on exercise electrocardiogram: The importance of QT ratio and QX/QT fraction in the diagnosis of ischaemic heart disease
Administration of digitalis in healthy controls. miscellaneous diseased and ischaemie heart patients produces ECG changes simulating ischaemic heart disease. Exercise further aggravates these changes, in digitalised patients, posing greater difficulty in ECG evaluation of ischaemic heart patients. The QT ratio and DX/QT fraction, in such situations can be of great help in differentiating the changes induced by ischaemia from those induced by digitals.
