Electrocardiogram - EKG

An electrocardiogram measures the rhythm of the heart.
Small stickers, called leads, are placed on the chest and sometimes on the arms and legs. The leads are attached to a monitor that measures the heart rythm.
When the rythm needs tp be measured over several hours or a day, the test equipment is called a Holter monitor. The Holter monitor is placed in a pouch the child can wear.

Echocardiogram - ECHO

An echocardiogram is a test of the strength and function of the heart.
The test is done using an ultrasound machine. A clear jelly is placed on the child’s chest. The technician will move a small round probe (transducer) around on the chest.
This probe sends sound waves to the heart, and the returning sound waves create a picture of the heart.

Pulmonary Function Tests - PFTS

Pulmonary function tests measure how well the lung are working. The test measures how much air the lungs can hold and how well your child can push air out of the lungs.
Your child will be asked to blow into a plastic mouthpiece connected to a machine. The machine measures the amount of air breathed in and teh force of the air breathed in and out. Your child will probably be asked to repeat the test a few times to get an accurate reading.
