[Scintigraphy of the myocardium following injection of thallium 201 during an exercise test. Value in the study of myocardial ischemia].
Thallium 201 is fixed rapidly by the healthy mocardium, and its emissions are easily recordable with a scintillation camera; it was used to discover and localise zones of ischaemia. This radio-isotope was injected into 40 patients during an exercise test. The results from this so-called exercise scintigraphy were compared with those of the exercise ECG, with the findings on coronary arteriography in 32 cases, and in 14 cases with those obtained by injecting thallium 201 into the patient while at rest (the so-called scintigram at rest). The results obtained from exercise scintigraphy correlate well with those from the exercise ECG and coronary arteriography. It would seem to have an important place in monitoring the permeability of aorto-coronary bypasses.
