Research funded by the Morris Animal Foundation has led to a new treatment for dogs with a specific type of arrhythmia (irregular heartbeat) caused by atrioventricular accessory pathways.

Researchers modified a minimally invasive technique used in human patients to help dogs with this rare but deadly heart irregularity.

Dr. Kathy N. Wright and her colleagues at the veterinary group MedVet published the results of their study in the Journal of Veterinary Internal Medicine. Their technique had a greater than 95 percent success rate in dogs with this specific type of arrhythmia.
