Abstract：Objective To investigate the relationship between the T-wave changes and serum potassium levels in patients with chronic kidney disease(CKD). MethodsThe CKD patients with peaked and shortened/symmetrical T-wave of which the amplitude was below 0.8 mV were selected as observation group while the hameochronous CKD patients without such T-wave change were considered as control group. The difference of serum potassium level and the incidence of hyperkalemia between the two groups were compared.ResultsThe serum potassium level was significantly higher in the observation group than that in the control group[5.6(5.2, 6.0) mmol/L vs. 4.2(3.8, 4.5) mmol/L], with statistically significant difference(P＜0.01). The incidence of hyperkalemia was separately 74.1% and 7.4% in the observation and control groups, also with statistically significant difference(P＜0.01). ConclusionFor the CKD patients with peaked and shortened/symmetrical T-wave of which the amplitude was below 0.8 mV in the ECG, their serum potassium levels were significantly higher compared with those CKD patients without such T-wave change The above ECG changes serve as good indicators of hyperkalemia in CKD patients.
