| 英文描述 | Tic or trembling in flank area that is synchronous with the heartbeat. Cause unknown. Often seen in endurance horses, and also reported with transit tetany, lactation tetany, and electrolyte imbalances with digestive disturbances. It is suspected that it may be related to acid base or electrolyte imbalance, possibly low calcium or alkalosis. This may be a recurrent problem in some horses. This syndrome has been reported in dogs following trauma or prolonged vomiting and idiopathic cases have also been seen. In dogs the problem may be short-lived or persist for months (Mainwaring). |
