A case of profound hypochloremic alkalosis with hypopotassemia is reported, showing electrocardiographic changes of electrical alternans of the repolarization wave (probably the U wave) without any change in the QRS complex. Transient concomitant P-pulmonale was noted. Hypopotassemia is discussed as a possible mechanism for the development of the electrical alternans.
报告了一例伴有低钾血症的严重低氯性碱中毒病例，其心电图显示复极波（可能是U波）电交替变化，而QRS波群无任何改变。同时还注意到短暂的肺型P波。低钾血症被认为是电交替发生的一种可能机制。
