摘　　要：目的研究高血钾患者与体检健康者间的T波时间和T/QT比值的差异,探讨高血钾患者的T波时间值和T/QT比值作为诊断高血钾的参考值的可行性。方法 63例高血钾患者和100例体检健康者通过12导心电图重叠波分别测出T波时间值、QT时间值及T/QT比值,并进行统计学分析。结果高血钾患者与健康体检者的T波时间值分别为104～131(117.27±13.42)ms、121～150(135.87±14.58)ms,差异有统计学意义(P﹤0.05);T/QT比值分别为0.28～0.34(0.31±0.03),0.34～0.42(0.38±0.03),差异有统计学意义(P﹤0.05)。结论高血钾患者与体检健康者相比,T波时间和T/QT比值有明显差异,高血钾患者T波时间值、T/QT比值可作为临床诊断高血钾的参考值。Objective To explore the difference in T-wave time and T/QT ratio between patients with hyperkalemia and healthy individuals.Methods T-wave time and T/QT ratio were tested by 12-lead ECG overlapping wave from 63 patients with hyperkalemia and 100 healthy individuals,respectively.Results T-wave time of hyperkalemia patients and healthy individuals were 104-131 ms and 121-150 ms,respectively.There were significant differences in T-wave time（P0.05）.T/QT ratios of patients with hyperkalemia and healthy individuals were 0.28-0.34 and 0.34-0.42,respectively.There were significant differences in T/QT ratios（P0.05）.Conclusion There were significant differences in T-wave time and T/QT ratios between hyperkalemic patients and healthy individuals,therefore,the study could provide a reference value of T-wave time and T/QT ratio for the diagnosis of hyperkalemia.
