In brief: Certain medications

Certain medications obscure the ekg changes, or the exercise capacity reducing the utility of the test.
Abnormalities of the resting ekg may also impair accuracy. Nuclear scans or echocardiographic images before and after exercise may be performed and may allow a diagnostic test even in these circumstances and also increase the diagnostic accuracy.
