An electrocardiogram is a test that measures heart rate and rhythm. It also can measure the type of heartbeat that you are having. It can spot possible blockages and show if you are having or have had a heart attack.
The test is painless and only takes a few minutes to perform. You will need to relax, lie on your back (if able) and tell the technician if you are having any discomfort. An EKG technician will apply small electrodes (sticky pads) on your chest, legs and arms. You will lie still, and the EKG machine will print a copy of your EKG. No special preparation is needed for this test.
This also is an electrocardiogram but may take a little longer for the EKG technician to perform. This test gives more detailed information regarding your heart rate and EKG pattern than a regular EKG. No special preparation is needed for this test.
