Plain-English summary
This case involves a pony that experienced a serious heart rhythm problem while under general anesthesia. The pony had a condition called myocardial fibrosis, which means there was scarring in the heart muscle, and this was discovered after the pony passed away. The heart issue was likely worsened by the anesthetic drugs used during the procedure. Unfortunately, the treatment did not work, as the pony did not survive.
Abstract
Ventricular dysrhythmias are more commonly associated with myocardial disease than are supraventricular dysrhythmias. Management of arrhythmias under general anesthesia is difficult because of the dysrhythmogenic effects of the anesthetic drugs. This report describes a severe ventricular dysrhythmia observed in a pony under general anesthesia, with a severe and old myocardial fibrosis found on postmortem examination.
