HOW IT WORKS Electrocardiogram measures electrical
activity of heart Shows:
o how fast heart is beatingo if its regular or irregularo strength and timing of electrical signalso size and position of chambers
Contains wires connected to machineo detect electrical signals of heart through skino trace heart rhythm on graph paper
