| signal-averaged electrocardiogram |
This is a noninvasive diagnostic test that records the electrical activity of the heart. It is similar to a regular electrocardiogram (EKG), but uses computer processing to record lower level signals not normally recorded by a standard EKG. Electrodes are placed on the chest area and connected to a recorder. The test helps the doctor predict the likelihood of high-risk patients developing life-threatening arrhythmias (irregular heart beats).
