目的分析急性心肌梗死合并糖尿病患者的QTc及QTcd的变化。方法选用急性心肌梗死合并糖尿病患者(A组)和急性心肌梗死无糖尿病患者(B组)入院时心电图,分别量取QTc及QTcd。结果 A组QTc及QTcd分别为(437.05±32.11)ms、(94.07±43.91)ms,B组分别为(420.41±32.72)ms、(76.53±30.92)ms,两组比较P值分别为0.05、0.058。结论急性心肌梗死合并糖尿病患者的QTc、QTcd较急性心肌梗死无糖尿病患者的QTc、QTcd有延长趋势,但需进一步研究。
Objective To analyze the changes of QTc and QTcd in patients with acute myocardial infarction complicated with diabetes mellitus. Methods The electrocardiogram (ECG) of patients with acute myocardial infarction complicated with diabetes mellitus (A group) and acute myocardial infarction without diabetes mellitus (Group B) were enrolled. QTc and QTcd were measured respectively. Results The QTc and QTcd in group A were (437.05 ± 32.11) ms and (94.07 ± 43.91) ms, respectively, and those in group B were (420.41 ± 32.72) ms and (76.53 ± 30.92) ms respectively, with P values of 0.05 and 0.058 . Conclusion QTc and QTcd in patients with acute myocardial infarction complicated with diabetes mellitus tend to have longer QTc and QTcd than those without diabetes mellitus in acute myocardial infarction, but further study is needed.
