Testing can be done on an outpatient basis and completed within 90 minutes.
Some medications can interfere with test results.
In some cases, testing can be performed while using the cardiovascular active medications to evaluate the effect of the treatment. In order to be most comfortable, patients should wear soft, non-restrictive clothing. Avoid clothing which may restrict blood flow, including stockings and corsets. The referring physician should advise the patient who has a cold, flu, or other illness, whether tests should be performed or re-scheduled to another time. Diabetic patients should have no evidence of hypoglycemia for 12 hours prior to testing.
