**2.4 Positioning of the animals**

The positioning of the animals is important to get an accurate ECG. The cattle should be kept in the standing position inside the trevis for an ECG examination. Animals affected with milk fever, diarrhea, lactic acidosis, Downer cow syndrome, etc. may be sternally or laterally recumbent. In such cases, animals may be subjected to the ECG examination in their current position.
