We knew he had an irregular heart beat (hoping it was AF and that I could take him to Washington University to get his heart 'shocked' back into a normal beat). I got a cardiologist from 5 hours away to come and perform a electrocardiogram and echocardiogram. He has Atrial Fibrillation, high blood pressure and an enlarged left side of his heart. Since there's an underlying heart issue and he's a large horse, shocking his heart isn't an option anymore. The vet is consulting with a few more teaching specialists to discuss the prognosis and plan of treatment options. I'll hear back later this week.
I'm pretty upset at the thought of not being able to ride him, and/or ultimately losing him. I think the plan of action will be putting him on lasix, digoxin and possible a potassium supplement.
Anyone out there have/had a horse with an enlarged heart (left side)? If so how did you and the horse manage it? Any, any, any advice will be appreciated. I love this gelding so much and he has so much potential this is devestating.
