Description of the Procedure
How Long Will It Take?
Will It Hurt?
- ECG and blood studies may be done.
- You will likely need to lie still and flat on your back for a period of time. A pressure dressing may be placed over the area where the catheter was inserted to help prevent bleeding. It is important to follow the nurses' directions.
- You will need to rest in bed until the sedative has worn off. Your heart rate and blood pressure will be monitored. You will also be checked for swelling or infections. If necessary, you may be given pain medicine. After resting for at least 4-6 hours, your doctor will let you know if you can go home that day or if you need to be admitted for more treatment or observation. If you are discharged on the same day as the test, you should have someone drive you home.
- Do not lift heavy objects or engage in strenuous exercise or sexual activity as directed by your doctor.
- Follow your doctor's instructions.
