An EKG (electrocardiogram) measures the electrical activity of the heart. Leads are placed on various parts of the body (6 on the chest, one on each arm and one on each leg) These leads carry electrical impulses from the heart and translates them onto a continuous strip graph.
EKG's are used to determine whether the heart is performing normally, if there are any conduction abnormalities, signs of insufficient blood flow to the heart, heart rhythm problems, and changes in activity caused by electrolyte imbalances (potassium, calcium, magnesium
