A resting heart rate above 80 bpm should be considered serious and a vet consulted immediately. The equine heart is a muscular pump that circulates blood throughout the body. Although the normal heart rate for most horses is 32 to 36 beats per minute, some horses have lower heart rates, 24 beats per minute, or maybe slightly higher heart rates, 40 beats per minute. [7], On the other hand, the Pearson correlation coefficient has been found to provide a link between oxygen uptake and echocardiographic measures. Produced in bone marrow, red blood cells are responsible for carrying oxygen to tissue and removing carbon dioxide, all via hemoglobin. Please take a moment to fill out our survey so we can continue to improve our website. The heart has an important role – it provides vital support to all other structures in the body – and when there is a medical issue involving the heart, it can drastically affect the horse… They range from simple minimal buttons to extravagant GPS systems, and come in hand-held, girth belt and electrode models, all equipped with an electronic training record.

The heart rates of 19 Thoroughbred racehorses have been continuously recorded during racing. Wireless wearable equine heart rate monitor for realtime ride feedback. However, studies on Thoroughbreds have shown that the proportion of skeletal muscle exceeds 50% of body weight, and so the energetic capacity of the muscular system far exceeds the capacity of the cardiovascular system to deliver oxygen.[4]. Heart Rate (HR) The normal heart rate of an adult horse at rest is 30-40 beats per minute (bpm). Remember, any excitement by the horse will increase the pulse rate.
