Detailed information on a cardiac catheterization procedure, including how the procedure is performed, reasons for the procedure, and pre- and post-evaluation instructions

Did you know that electrical currents flow throughout your body? Because the strongest of these travels through your heart, doctors are able to monitor your heart by placing electrical sensors on the surface of your skin. They do this by giving you an electrocardiogram -- abbreviated either ECG or EKG (from the original German spelling of the word).

When you feel chest pain from blocked arteries, you might see an interventional cardiologist for treatment.
