Four Quarter Horse foals ranging in age from 6 days to 2 months were determined to have upper airway stridor secondary to polymyopathy suspected to be hyperkalemic periodic paralysis. Electromyography revealed spontaneous muscle activity in all muscles examined. Electromyographic findings were similar in the dams of 3 foals (No. 1, 3 and 4). Hyperkalemia was found in foals 1 and 4. Endoscopically, the upper airway stridor in foals 1 and 3 was confirmed to be attributable to laryngeal and pharyngeal collapse or spasm. Foals 1, 2, and 3 were treated with acetazolamide. Foal 4 was not treated, at the owner's request. Foals 2 and 3 improved with treatment, foal 4's condition was static, and foal 1 required a tracheostomy and laryngeal surgery to manage its upper airway stridor.
4匹年龄在6天至2个月之间的美国夸特马驹被诊断为患有上呼吸道喘鸣，继发于疑似高钾性周期性麻痹的多肌病。肌电图显示，在所有检查的肌肉中均有自发肌肉活动。3匹驹（第1、3和4号）的母马肌电图检查结果相似。在第1和第4号驹中发现了高钾血症。在内镜检查中，第1和第3号驹的上呼吸道喘鸣被证实是由于喉和咽塌陷或痉挛所致。第1、2和3号驹用乙酰唑胺治疗。根据主人的要求，第4号驹未接受治疗。第2和第3号驹经治疗后病情改善，第4号驹病情无变化，第1号驹需要进行气管切开术和喉部手术来处理其上呼吸道喘鸣。
