Hyperthyroid cats were examined by electrocardiography, radiography, and echocardiography for the presence of cardiomegaly. These examinations were performed at the time of the initial diagnosis of hyperthyroidism and repeated during the course of antithyroid medication and after thyroidectomy was done. If the hyperthyroid cats had cardiomegaly, reduction in cardiac size was detected once the euthyroid state was reestablished. This decrease in size was appreciated electrocardiographically and radiographically. The echocardiogram demonstrated a decrease in left atrial size. A consistent decrease in left ventricular wall thickness was not observed by the echocardiogram, although 2 cats did have resolution of free wall hypertrophy.
对甲状腺功能亢进的猫进行了心电图、X光摄影和超声心动图检查，以确定是否存在心脏肥大。这些检查在甲状腺功能亢进症初诊时进行，并在抗甲状腺药物治疗期间及甲状腺切除术后重复进行。如果甲状腺功能亢进的猫有心脏肥大，一旦恢复到甲状腺功能正常状态，就能检测到心脏大小缩小。这种大小的减小通过心电图和X光摄影得以确认。超声心动图显示左心房大小减小。超声心动图未观察到左心室壁厚度持续减小，不过有2只猫的游离壁肥厚得到了缓解。
