In which position should a dog be placed for an ECG?

For an electrocardiogram (ECG) in dogs, the correct positioning is typically right lateral recumbency. This position allows for optimal exposure of the thoracic area, ensuring that the electrodes can be placed correctly on the forelimbs, hind limbs, and along the chest.

When the dog is in right lateral recumbency, the heart is more accessible to the electrodes, facilitating accurate readings of the electrical activity of the heart. Additionally, this position helps to reduce movement artifacts that could interfere with the ECG results, which is crucial for obtaining clear and interpretable data.

While other positions like dorsal recumbency or left lateral recumbency may be used in some situations, they do not provide the same level of ease for electrode placement or heart visibility as right lateral recumbency. Sternal recumbency is also less commonly used for ECGs due to similar limitations with ill-defined electrode placement and potential discomfort for the animal.
