The procedure is done either in the Mercy Endoscopy unit, or the Mercy CCU. It is important to have nothing to eat or drink for 6 hours prior to the test. The throat is sprayed with some local anaesthetic and intravenous sedation is given. The test usually takes 10-20 minutes.
Observation is required for a short time after the test. The patient is advised not to drive for 24 hours (because of the sedation). A report will be sent to the referring doctor, and the cardiologist who has performed the test will explain the results after the procedure.
