An electrocardiogram (ECG or EKG) is a recording of the electrical activity of the heart. It is a safe, noninvasive procedure that uses clips (electrodes) placed on the skin over the chest and legs. An ECG is used commonly to evaluate the heart rhythm and identify abnormalities (arrhythmias) in the heartbeat. It may also help to identify enlargement of the heart, a common finding with many heart diseases. We have the ability to submit ECG readings electronically for review by a veterinary cardiologist. Additionally, continuous ECG monitoring is performed during every anesthetic procedure.
