Signal Average EKG

What is a Signal Average Electrocardiogram (EKG)?

A signal-average electrocardiogram is a more detailed type of EKG. During this procedure, multiple EKG tracings are obtained over a period of approximately 20 minutes in order to capture occasional abnormal heartbeats. A computer captures all the electrical signals from the heart and averages them to provide the physician more detail regarding how the heart’s electrical conduction system is working.

Purpose of a Signal Average Electrocardiogram EKG:

• Assess the potential for dysrhythmias/arrhythmias (irregular heart rhythms) in certain medical situations
