We perform an EKG on each child seen at our office. This is a non-invasive procedure that does not hurt your child. Special stickers placed on the child's chest connect via wires to a machine that reads the electrical activity of the heart. The machine then prints out the electrical activity in the form of spikes and waves on paper, like the picture above. This tells the cardiologist many things about your child's heart, including how fast it is beating, how regularly it is beating, and if there are any problems with the electrical system of the heart.
