Solution
The symptoms that would indicate that the exercise electrocardiography (ECG) test should be stopped immediately and the client be monitored for myocardial ischemia include:
-
ST-segment depression on the ECG: This is a classic sign of myocardial ischemia. It indicates that the heart muscle is not getting enough oxygen.
-
T-wave changes on the ECG: Changes in the T-wave can also indicate myocardial ischemia. The T-wave represents the repolarization (or recovery) of the ventricles. Changes in this wave can indicate a problem with this recovery process, which can be due to ischemia.
While fatigue (1) and dyspnea (2) can be associated with heart problems, they are not specific to myocardial ischemia and can occur with any strenuous exercise. Similarly, a heart rate increase from 80 to 95 (4) is expected during exercise and would not necessarily indicate a need to stop the test.
