Outpatient Procedure

Once your doctor has requested a cardiac test, you can call (303) 788-5100 to schedule your appointment at Swedish's Cardiac Testing.

Check In

In general, patients should arrive 30 minutes before their scheduled appointment and check in at Admissions off of the main lobby on the 1st floor prior to going up to Cardiac Testing. If your procedure requires you to check in more than 30 minutes in advance of your appointment, a representative from Cardiac Testing will let you know beforehand. Please bring your driver's license, insurance card(s) and copay to Admissions for check in.

Once checked in, you will be directed to Cardiac Testing on the 4th floor. From Admissions, proceed west to the Chapel elevator, go to the 4th floor and Cardiac Testing is located just north of this elevator.


Prior to arriving at Swedish for your procedure, please contact your insurance provider to determine the amount of your copay for the procedure. Your copay will be due at the time of service.


We recommend that patients use our free valet parking services located at the main entrance to Swedish or self-park directly across the street in the South Parking Garage. Once parked, you will have a significant walk to Admissions and then to Cardiac Testing; if you need a wheelchair, please ask the valet parking attendants or the volunteers at the main entrance to get one for you.
