What does "HR" refer to in physical examinations?

Heart rhythm
Heart rate
Heart recovery
Heart response

The correct answer is: Heart rate

In the context of physical examinations, "HR" primarily stands for heart rate. The heart rate is a vital sign that indicates how many beats per minute the heart is pumping. It is a crucial parameter to monitor during examinations to assess the overall cardiovascular health of an animal. The measurement of heart rate can provide important information regarding the animal's health status, including stress levels, pain assessment, and potential underlying medical conditions. This value is often evaluated alongside other parameters like respiratory rate and temperature to get a comprehensive picture of the animal's well-being. Understanding heart rate is essential for veterinary technicians as it can directly influence treatment decisions and help in monitoring the effects of drugs or other interventions during clinical examinations.
