Electrocardiogram⁄ EKG

What is an EKG?
An EKG is a recording of the electrical activity occurring within the heart each time it contracts.

What can be detected on an EKG?
This test can reveal many things about your child’s heart such as heart rate, rhythm, and various other anatomical findings.

How is the test performed?
A technician will place electrodes (stickers) on various parts of the chest, arms and legs.  They do not hurt while being placed on or coming off, and your child will not feel anything while the test is being performed.  The electrodes are attached to wires that are connected to a machine.  It will then make a print out of the electrical activity occurring each time the heart contracts.

How long will the test take?
It takes approximately two to three minutes to attach the electrodes and only about 30 seconds to record the heart beats.  Your child must lie as still as possible or an accurate recording will not be possible.  Infants and toddlers may drink a bottle to help them lie still. 

How will I be informed of the results?
Within 24 hours of the test being performed, a pediatric cardiologist will interpret the EKG.  You will receive the results from the doctor who ordered the test, usually your pediatrician or a pediatric cardiologist.
