Whereas the electrocardiogram (ECG) changes in hypokalemia are well known, they often receive less attention than the more striking features of hyperkalemia. Furthermore, there is a need for further discussion as to the subtleties of ECG changes that can aid in the differential diagnoses. This case study presents the ECG changes of a patient with severe hypokalemia due to diarrhea. It highlights how bifid T-waves in hypokalemia can be distinguished from other conditions such as coronary artery disease or pericarditis. Furthermore, it also shows the gradual reversal of ECG changes in the same patient when potassium is normalized.
虽然低钾血症时的心电图（ECG）变化广为人知，但与高钾血症更显著的特征相比，它们往往较少受到关注。此外，对于有助于鉴别诊断的心电图变化的细微之处，仍有进一步讨论的必要。本病例研究展示了一名因腹泻导致严重低钾血症患者的心电图变化。它突出了低钾血症时双峰T波如何与冠状动脉疾病或心包炎等其他情况相鉴别。此外，它还显示了该患者血钾恢复正常时心电图变化的逐渐逆转。
