Electrocardiogram (ECG or EKG)
An Electrocardiogram is a tracing of the electrical activity of a patient’s heart. The electric current is produced by the contraction of the heart muscle and is recorded onto paper for the physician’s review. The test generally lasts less than one minute and involves electrodes being placed on the patient’s chest, arms, and legs.
A Rhythm Strip is similar to an electrocardiogram, except the physician may look at one particular electric current of the heart instead of all of it at the same time. The length of the procedure will vary, depending on what the physician needs and is looking for.
