A. Room Monitors and Telemetry:
If you are in the Intensive Care Unit or the Telemetry Unit, electrocardiographic (EKG) electrodes (sponge pads) will be placed on your chest. The EKG electrodes will be connected to a monitor. The monitor gives the nurses and doctors a continuous picture of your heart's electrical activity - information that helps plan your therapy. The EKG electrodes are very sensitive, so don't be frightened if your movement activates the monitor's alarm. This is a safety feature that alerts physicians and nurses regarding any significant changes in the rate or rhythm of your heart beat. A Holter monitor may also be ordered by your physician. This monitor is worn by the patient and retains a constant record of your heart rhythm on a tape recorder.
An electrocardiogram (EKG) gives an electrical "picture" of how your heart is working. The test requires only that you lie still while the technician puts electrodes (sponge pads) on your chest. The test takes about five minutes.
Preparation for electrocardiogram: None
C. Stress Test (Exercise Test / Stress Echo done in office):
A stress test allows us to see how your heart is working during the stress of exercise, and just after exercise. The exercise device or stress test can be performed on a treadmill.
During the test, you are connected to a monitor by EKG electrodes (sponge pads). A doctor watches and evaluates you very closely. The Standard Bruce Protocol will be used, which entails changes in speed and elevation every three minutes. Feel free to communicate to your physician how you are feeling throughout the test. After the stress test is over you will return to a table for post-exercise EKG and to relax.
Preparation for stress test:
1. Nothing to eat or drink for 3-4 hours prior to taking the test (other than medication).
2. Wear good walking shoes (rubber soles, if possible).
3. Some medication may be withheld temporarily prior to the stress test. You will receive specific information from the nurse or physician prior to taking the test.
During the stress test, it is important to let the physician or nurse know if you:
