Transtelephonic Monitoring (TTM)
Explanation of the Test
This test is done to monitor your heart's electrical activity over a 30-day period while performing normal activities. First, your chest will be cleaned thoroughly with alcohol and rubbed with an abrasive lotion (chest hair will be shaved if necessary). Three small pads (electrodes) will be placed on your chest. Wires will connect these pads to a walkman- or pager-sized monitor that will store the electrical activity of the heart. You will be asked to transmit the tracing over the telephone and to wear the monitor as often as possible. You may take off the monitor to shower or bathe and should reapply soon after.
Preparation
A two-piece outfit should be worn so that the wire can come out from the patches to the recorder. If a one-piece outfit is worn, it should have buttons (not a zipper) down the front to accommodate the wire.
General Information
- The application of the monitor takes about 30-45 minutes.
- Avoid exposing the monitor to extremely cold weather. Wear the monitor beneath a coat if necessary.
- You should not shower or swim while wearing the monitor.
- Any further questions about the test may be answered by your physician.
- The results will be sent to your doctor within 24 hours from when the monitor is returned.
