Answer

Interpretation should include exercise capacity and clinical, hemodynamic, and ECG response. The occurrence of ischemic chest pain consistent with angina is important, particularly if it forces termination of the test. The classic criteria for visual interpretation of positive stress test findings include the following:

  • J point – This is defined as the junction of the point of onset of the ST-T wave; it is normally at or near the isoelectric baseline of the ECG

  • ST80 – This is defined as the point that is 80 msec from the J point

  • Depression of 0.1 mV (1 mm) or more

  • ST-segment slope within the range of ± 1 mV/sec in 3 consecutive beats
