目的：总结低血钾症的心电图特征，以探讨心电图对低血钾的诊断价值。方法：回顾性分析2011年1月-2013年10月收治的低血钾症患者118例的临床及心电图资料。结果：随着低血钾症严重程度的增加，心电图呈特征性的 ST 段压低、T 波振幅降低、U 波振幅增高、T-U 融合、P 波和 QRS 波的振幅和时限增加、P-R间期和Q-T 间期延长及心律失常。结论：低血钾症具有特征性的心电图改变，有助于低血钾的快速诊断。

To summarize the electrocardiogram characteristics and to explore the clinical diagnostic value of patients with hypokalemia. Methods: The clinical and electrocardiogram data of 118 patients with hypokalemia were retrospectively analyzed from Jan 2011 to Oct 2013. Results: With the severity increasing of hypokalemia, the electrocardiogram was characteristic of low ST segment , T wave amplitude reduced , U wave amplitude increased , T-U fused, P wave and QRS wave amplitude and duration increased,P-R and Q - T extended and arrhythmia occured. Conclusion: It is helpful to diagnose hypokalemia rapidly because of characteristic changes of the electrocardiogram.
