An electrocardiogram (EKG or ECG) is an easy way to check the electrical system of your heart. Because the actual pumping action normally follows the electrical impulses closely, we can get an idea of how your heart is beating, as well: too fast, too slow, or irregularly. Your <pulse> is another way of testing it, and if it doesn't match the EKG rhythm, you may need further testing and treatment to sort out why.

By looking at the heart from multiple angles (usually 12 different "leads"), we can get a better idea of how well its "circuitry" is working overall, and gain more subtle clues as to problems with the pump - if it's overworked or unbalanced, for instance.

We don't just obtain an EKG when you come in with a problem. If we feel you are at enough risk for problems, we may need to obtain one as well. And if we catch a problem before it starts to affect your life, so much the better.
