How to perform transvenous electrical cardioversion in horses with atrial fibrillation.
Abstract: Electrical cardioversion of atrial fibrillation is a well-established technique for restoration of sinus rhythm in humans. While transthoracic cardioversion is more commonly used, transvenous electrical cardioversion (TVEC) has been reported as having higher efficacy at substantially lower energy levels. In horses, treatment of atrial fibrillation has essentially been limited to the administration of quinidine salts either orally or intravenously. TVEC provides an alternative to quinidine salts, especially for those animals in which quinidine is neither effective nor tolerated. The present report details this technique in horses, discusses possible complications of the procedure, and provides guidance for successful outcome. Still and video images are used to illustrate details with regard to TVEC techniques in horses. Please view supplemental material for the videos.

This research article focuses on a more effective treatment for atrial fibrillation in horses, called transvenous electrical cardioversion (TVEC), which was previously only commonly used in humans.
Introduction
- The traditional treatment for atrial fibrillation in horses has been the administration of quinidine salts, either orally or intravenously.
- However, there may be instances where this treatment is not effective or is not well-tolerated by the horse. This has prompted researchers to look for alternative treatments.
- Transvenous electrical cardioversion (TVEC) has been identified as one such alternative. This treatment method, while more commonly used in humans, is reported to have higher efficacy while using substantially lower energy levels in horses.
Procedure
- The research article not only details how to perform TVEC in horses but also discusses potential complications that may arise during the procedure.
- The aim is to provide guidance to veterinarians and other professionals so they can successfully treat horses using this method.
- Still and video images are also included in the research to help illustrate the TVEC procedure in horses. These documents serve as additional resources for guidance and reference.
Conclusion
- TVEC offers a potentially more effective and safer treatment option for horses suffering from atrial fibrillation, especially in cases where traditional methods are ineffective or not tolerated.
- The research article thus provides a comprehensive guide for performing the procedure, highlighting its benefits and potential complications. This is expected to help animal health professionals in implementing this technique with greater confidence and success.
