Some patients are unable to perform physical exercise. Furthermore, in patients with resting ECG abnormalities the exercise ECG is associated with low sensitivity and specificity. If the ECG made during exercise testing does not show any abnormalities myocardial ischemia becomes unlikely as cause of the complaints. If the diagnosis is still in doubt, the following additional tests may be performed. | Some patients are unable to perform physical exercise.

If the ECG made during exercise testing does not show any abnormalities myocardial ischemia becomes unlikely as cause of the complaints. If the diagnosis is still in doubt, the following additional tests may be performed. | |||
#Exercise echocardiography means that an echocardiography is made before and during different stages up to peak exercise in order to identify wall motion abnormalities. <Cite>REFNAME12</Cite> An alternative is pharmacological stress testing using dobutamine. | #Exercise echocardiography means that an echocardiography is made before and during different stages up to peak exercise in order to identify wall motion abnormalities. <Cite>REFNAME12</Cite> An alternative is pharmacological stress testing using dobutamine. | ||
