Electrocardiogram (ECG)

An ECG is a measuring device used to diagnose heart disease. It measures the electrical impulses emitted by the heart's activity.

Areas of application

In veterinary medicine, an ECG is mainly used to diagnose cardiac arrhythmias and for intensive monitoring. Unlike humans, heart attacks are rare in animals.

Procedure

In small animals, the examination is performed with the animal lying on its right side; in large animals, the animal stands. It is important that the animals lie or stand on a non-conductive surface. The impulses are recorded by electrodes that are attached to the animal's skin. The currents are then displayed in a curve that represents the heart function.

Special ECG methods

Stress ECG

If symptoms only occur during physical activity, a stress ECG is recommended. This involves recording an ECG while the animal is under stress for a certain period of time.

24-hour ECG

A 24-hour ECG, also known as a Holter ECG, can be used to measure an animal's heart activity over a whole day or even longer under normal conditions. This type of ECG is used to diagnose certain diseases at an early stage or to record fainting spells and episodes of weakness. For this purpose, adhesive electrodes are attached to the side of the chest and the device itself is attached to the animal's back with a small backpack. This means that the animal does not need to be admitted to hospital for the examination.

Event recorder

An event recorder is used to detect cardiac arrhythmias that occur only occasionally and cannot be detected by an ECG during symptom-free periods. The device can be attached externally or implanted under the skin through a small incision. An event recorder can remain on or in the animal for a certain period of time and continuously records ECG data for a few minutes at a time.
