will be done to check the electrical activity of your heart.
Description of Test
The test steps depend on how it will be done:
—A small device will be strapped to you. Wires from it will be attached to small sticky pads (electrodes) on your chest. You may be taught to replace them or asked not to take them off during the test. Some devices have an event button. You will push the button each time you have a symptom that bothers you.
You will need to keep a diary of the things you do for the next 24 to 48 hours. You will return the device and your diary.
—The electrode may be a wrist band, finger attachment, or chest plate. It records many minutes at a time, then starts over. You will push a button during or after an event to save the data. There is an implantable version that records longer periods of time. It is surgically placed under your skin.
—This device is only used when you have symptoms. It may be a wrist band with a button or a pager-sized device that you press onto your chest. Some of these are connected to a 24 hour base that can find a problem right away and respond to an event when you activate the signal.
Mobile cardiac outpatient telemetry
—A special service monitors your heartbeat at all times. It will respond right away when it finds a serious problem.
You will need to stay away from things like magnets, metal detectors, high-voltage wires, microwave ovens, and electric devices. They may cause problems with the test.
