At PHD Veterinary Services, we are committed to providing top-tier diagnostics and treatment options for equine cardiac health. Recently, we evaluated a horse for a suspected cardiac arrhythmia, and I wanted to take a moment to share insights into the diagnostic process, treatment considerations, and the overall impact of heart conditions in horses.
Diagnosing Cardiac Conditions in Horses
When assessing a horse’s cardiac health, we utilize a combination of diagnostic tests, including:
Electrocardiogram (ECG): Evaluates the electrical activity of the heart and detects arrhythmias.
Echocardiogram: A detailed ultrasound of the heart used to assess its structure and function.
Thoracic Auscultation: Listening to heart sounds with a stethoscope to identify irregular rhythms.
In this particular case, thoracic auscultation detected an abnormal cardiac rhythm, and an electrocardiogram confirmed atrial fibrillation. The echocardiogram revealed normal heart structure and function.
How Do Cardiac Arrhythmias Affect Horses?
A horse with an arrhythmia may experience:
-Decreased performance and stamina
-Poor recovery after exercise
-Failure to thrive
-Reduced life expectancy
While there is no breed predisposition, atrial fibrillation is more commonly seen in Thoroughbred racehorses under five years old.
What Are the Risks of Untreated Cardiac Arrhythmias?
If left untreated, cardiac arrhythmias can lead to:
Continued poor performance
Congestive heart failure
Warning Signs of Cardiac Issues in Horses
Owners should monitor their horses for these potential signs of heart problems:
Poor recovery after exercise
Decreased stamina during workouts
Failure to thrive
Treatment and Management of Atrial Fibrillation
For this case, we considered two treatment options:
Chemical Conversion – Using medication to restore a normal heart rhythm.
Electrical Conversion – A more advanced procedure that resets the heart’s rhythm using electrical stimulation.
If conversion back to a normal sinus rhythm is not possible, retirement may be the best course of action, as continued work can put the horse at significant risk.
Long-Term Monitoring for Horses with Arrhythmias
Routine monitoring is critical for horses diagnosed with a cardiac irregularity. This includes:
Regular auscultation (listening to the heart) by a veterinarian.
While there are no specific preventative measures, twice-yearly physical exams by a veterinarian can help detect issues early.
How Does PHD Veterinary Services Approach Cardiac Evaluations Differently?
At PHD Veterinary Services, we have all the necessary diagnostic equipment to accurately assess and diagnose cardiac conditions in horses. This allows us to provide precise evaluations and tailored treatment plans.
Our specialized tools and expertise include:
Electrocardiogram (ECG): Provides real-time rhythm assessment.
Echocardiogram: Evaluates heart structure and function.
Internal Medicine Specialist: Expertise in equine cardiology for accurate diagnosis and management.
This comprehensive approach allows us to deliver the highest level of care for horses with cardiac concerns.
Looking Ahead
The outcome for this particular case is still pending, but our goal remains the same: to provide accurate diagnoses, personalized treatment plans, and the best possible care for each horse.
