An electrocardiogram (ECG or EKG) uncovers valuable information about the heart’s electrical activity. Electrodes, attached to a patient’s chest, show this activity in the form of “waves” that are recorded on paper or viewed on a monitor. Cardiologists interpret the waves to determine heart muscle damage or how much blood and oxygen is being supplied to the heart. Specific ECG/EKG patterns also can provide clues to the size of the heart’s chambers, and if they have become enlarged.
