How do you treat atrial fibrillation in horses?

Transvenous electrical cardioversion is our preferred method for conversion of atrial fibrillation in horses. For this procedure, a catheter is placed in the jugular vein.

Is quinidine safe for horses with atrial fibrillation?

Once diagnosed, atrial fibrillation can be treated with the drug quinidine, but there are potential side effects such as ataxia, nasal edema, colic, hives, laminitis and rarely death. The University of Florida Large Animal Hospital is the only equine veterinary clinic in Florida…

How do vets treat atrial fibrillation in dogs?

Treatment methods may include: Quinidine is the drug of choice to treat atrial fibrillation by many veterinarians. Your veterinarian will explain the dosage recommendations, as well as the possible side effects. Side effects of this effective medication may include colic, nasal edema, ataxia, hives, and laminitis.

What is the best treatment for AFIB in horses?

Three treatment options are available for AF in horses, with the exception of horses with CHF: 1. Pharmacologically converting the arrhythmia, with the most common drugs being either quinidine gluconate or quinidine sulfate 2.

How effective is quinidine for atrial fibrillation in horses?

In terms of recovery, quinidine tends to work with a good success rate for many horses. The sooner the atrial fibrillation is diagnosed, the more effective treatment will be for your horse. If your horse has had atrial fibrillation for an extended period of time, treatment may be less effective, but may still work.

What is atrial fibrillation (a-fib)?

Atrial fibrillation (or “A-Fib”) is an abnormal rhythm of the heart and is one of the most common cardiac problems in horses.

How to tell if a horse has atrial fibrillation?

Diagnosis of Atrial Fibrillation in Horses. If your horse has a heart rhythm that is irregular, he may hear it via his stethoscope. He may then perform a test known as an electrocardiogram. An electrocardiogram will confirm your horse’s irregular heartbeat, or arrhythmia, and will aid him in his diagnosis.

How does Electrocardioversion work on a horse?

In electrocardioversion, the horse is placed under anesthesia, and a catheter is inserted into your horse’s jugular vein in order for electrical leads to be placed into the heart. A properly-timed, synchronized shock is delivered to aid the sinus rhythm to return back to normal. In some cases, the procedure needs to be repeated over time.

How much plasma Quinidine should a horse have?

Plasma quinidine concentrations within 1 hour of conversion of AF to sinus rhythm ranged from 1.7 to 7.5 micrograms/mL (mean, 4.05 +/- 1.6) and ranged from 1.7 to 4.7 micrograms/mL in 97% of horses.

What is quinidine for atrial fibrillation?

Quinidine is the drug of choice to treat atrial fibrillation by many veterinarians. Your veterinarian will explain the dosage recommendations, as well as the possible side effects.

Is quinidine safe for horses?

This method of treatment is also quite costly, and since quinidine is effective for many horses, it is often decided to attempt the medication at the beginning of your horse’s treatment. If you see any new symptoms or any behavioral changes within your horse that may not be related to the medication he is taking, contact your veterinarian.

How to treat atrial fibrillation in horses?

Your veterinarian may be able to recommend a heart specialist who can treat the atrial fibrillation with electrocardioversion. Electrocardioversion may be effective in horses with this condition that do not respond well to quinidine. This is a costly procedure and highly selective.

What is included in the physical examination of a horse?

The physical examination includes using a stethoscope to listen to the sounds made by the horse’s internal organs, especially the heart, lungs, and abdominal organs.

How do vets assess a horse’s heart?

Auscultation (listening to) the horse’s heart is a quick and simple way of assessing the heart, although not without its problems. Here is a list of what your vet is assessing when he listens to your horse’s heart: This is expressed in beats-per-minute, usually worked out by counting the number of beats in 15 seconds, then multiplying by four.

Why would you give a dog atrial fibrillation medicine?

Its main indication in veterinary medicine is to treat atrial fibrillation. It has the potential to convert atrial fibrillation to sinus rhythm and is used for this indication in horses. In dogs, it is used to facilitate synchronized cardioversion of atrial fibrillation.

Can a dog with atrial fibrillation have sinus rhythm?

It has the potential to convert atrial fibrillation to sinus rhythm and is used for this indication in horses. In dogs, it is used to facilitate synchronized cardioversion of atrial fibrillation. It is not typically used for rate control of chronic atrial fibrillation in dogs or horses, or to treat ventricular arrhythmias.

What is the most common arrhythmia in horses?

Abstract: Atrial fibrillation is the most common performance-limiting arrhythmia in the horse. Detailed cardiovascular evaluation will help guide prognosis and treatment. Many affected horses have lone atrial fibrillation (no predisposing cardiac abnormalities).

What is the prognosis of atrial fibrillation in horses?

Many affected horses have lone atrial fibrillation (no predisposing cardiac abnormalities). These horses have a good prognosis for return to performance if sinus rhythm can be restored.

How do you treat a dog with a heart arrhythmia?

Therefore, some dogs with ventricular arrhythmias must be treated with antiarrhythmics (e.g. sotalol). Most often to determine if this is required electrocardiograms are recorded and 24-hour electrocardiograms are monitored ( Holter monitoring ).

Is atrial fibrillation in dogs dangerous?

Atrial fibrillation is associated with increased risk of cardiovascular mortality. Atrial fibrillation (AF) is the most common non-physiological arrhythmia in dogs and humans. Its high prevalence in both species and the impact it has on survival time and quality of life of affected patients, makes it a very relevant topic for medical research.

How common is atrial fibrillation in horses?

Atrial fibrillation (AF) is the most common clinically relevant arrhythmia in horses, with a reported prevalence up to 2.5%. The pathophysiology has mainly been investigated in experimental animal models and human medicine, with limited studies in horses.

How do you know if your horse has a-fib?

Horses that have abnormal heart rhythms will undergo a full workup, including physical examination, blood work, electrocardiogram (“ECG”), and echocardiogram (“echo”) to diagnose A-Fib and rule out any other underlying conditions.

How much Quinidine sulfate to give a horse?

Forty-one horses were treated for atrial fibrillation (AF) with 22 mg/kg quinidine sulfate via nasogastric tube every 2 hours until conversion to sinus rhythm, a cumulative dose of 88 to 132 mg/kg had been administered in 2-hour increments, or the horse had adverse or toxic effects from the drug.

How to do transvenous cardioversion on a horse?

Transvenous electrical cardioversion is our preferred method for conversion of atrial fibrillation in horses. For this procedure, a catheter is placed in the jugular vein. Electrical leads are then threaded into the right atrium and left pulmonary artery using echocardiographic guidance with the horse standing.

How does a defibrillator work on a horse?

Once the defibrillator shock button was pressed the defibrillator delivered the requested shock on the next “R” wave, allowing precise timing of shock delivery. Unfortunately in the horse, occasional detection of the T wave as an R wave occurred ( Fig. 9 ).

What are the symptoms of atrial fibrillation in horses?

What are the symptoms of atrial fibrillation in horses? 1 Poor performance. 2 Shortness of breath. 3 Easily exhausted. 4 Coughing. 5 Discharge from nose. 6 … (more items)

What drugs can cause digoxin toxicity in horses?

Antacids, cimetidine, metoclopramide, oral neomycin, and penicillamine may decrease digoxin absorption. Diazepam, quinidine, anticholinergics, succinycholine, verapamil, tetracycline, and erythromycin may lead to increases in digoxin levels. Drugs that decrease serum potassium may predispose horses to digoxin toxicity.
