YOU ARE OBSERVING
Heart Rate, Pulse Rapid, Greater than 48 BPM at Rest (in Adult)
Summary
Horses experiencing abdominal pain (colic), low blood pressure, blood loss, primary heart problems, and poor respiratory gas exchange all might exhibit elevated heart rates. Importantly, though, heart rate also increases drastically with stress, exercise or excitement. For that reason, it is critical that the examiner always double check an elevated heart rate when the horse is relaxed. Certain medications will also cause a drastic rise in heart rate.
A normal heart rate or pulse for average adult horses at rest ranges from 28 to 44 beats per minute (bpm). Heart rates exceeding 50 bpm in an otherwise normal seeming horse may indicate a problem and should prompt you to call your vet to discuss your findings. In a normal horse, the heart rate should be the same as the pulse rate. Smaller horses and foals usually have more rapid heart rates.

What To Do
Know what your horse's normal heart rate is in health, so that you have a baseline to compare to when you suspect a problem. Double check the rate when the horse is relaxed. In a recently exercised horse, the length of time it takes for heart rate to return to baseline depends to a great extent on fitness.In most cases, there are other primary signs that prompted a horse owner to take the heart rate in the first place. The other signs may be more indicative of the nature of disease. Heart rate elevation is a common finding in many conditions but can be a valuable indicator of the severity of illness.
