Electrocardiogram (also referred to as an ECG or EKG)

ECG is an essential tool in veterinary cardiology for evaluating heart conditions in animals. It provides valuable information about the electrical activity of the heart, aids in diagnosing arrhythmias, and assists in monitoring the effectiveness of treatments.


During an ECG, electrodes are placed on specific locations of the animal’s body, typically on the limbs and chest. These electrodes detect the electrical signals produced by the heart as it contracts and relaxes. The signals are recorded and displayed as a waveform on an ECG machine or monitor.


By analyzing the ECG waveform, we can determine the heart rate, identify abnormal heart rhythms (arrhythmias), and evaluate the conduction of electrical impulses through the heart. An abnormal ECG can help in identifying the origin of abnormal heartbeats and guide further diagnostic investigations and treatment.
