[Computerized analysis of ST segment during exercise. Interpretation of "saw tooth" appearance].
The authors report original appearances (sinusoid or "saw tooth" aspect) of computerised analysis of the ST segment in 3 cases, corresponding to ST changes during exercise stress testing. This is due to alternating ST elevation and depression probably related to abnormal vasomotor tone given the fact that the recording was normalised by coronary vasodilator therapy.
