Three young Standardbred pacers with atrial fibrillation were treated with quinidine sulphate (QS) by stomach tube. They were given 10g QS every 2 hours until cardioversion was achieved. Total doses varied between 20 and 30 g. No premedication was given nor any follow up treatment after return to sinus rhythm. All horses were given 3 months rest after the treatment, and when electrocardiographed then, and at 6 months, showed normal sinus rhythm. As all 3 horses won races after cardioversion and showed subsequent normal electrocardiograms it seems likely that atrial fibrillation can occur without detectable pathological changes in the heart.
对3匹患有心房颤动的标准赛马用胃管投予硫酸奎尼丁（QS）进行治疗。每2小时给它们喂服10克QS，直至实现心脏复律。总剂量在20至30克之间。复律前未给予任何预处理，恢复窦性心律后也未进行任何后续治疗。所有马匹在治疗后均休息3个月，之后进行心电图检查时，以及在6个月时，均显示窦性心律正常。由于所有3匹马在心脏复律后都赢得了比赛，且随后心电图显示正常，因此似乎心房颤动可能在心脏未检测到病理变化的情况下发生。
