A new study is exploring the atrial fibrillatory rate (AFR) as predictor of recurrence of atrial fibrillation in horses treated medically or with electrical cardioversion.
High AFR is associated with failure of quinidine cardioversion and AF recurrence after successful transvenous electrical cardioversion. As a noninvasive marker that can be retrieved from surface ECG, AFR can be clinically useful in predicting the probability of responding to quinidine treatment as well as maintaining SR after electrical cardioversion.
