Abstract Objective To explore the diagnostic value of changes on electrocardiogram(ECG) for young and middle-aged patients with hyperthyroidism.MethodsECG data of 75 outpatients who were diagnosed in our hospital with hyperthyroidism for the first time were analyzed. Meanwhile, 75 case of normal persons who were matching with the 75 outpatients in genders and ages were enrolled as the control group and their ECG data were also analyzed. ResultsThere were ECG changes in 37 cases(accounting for 49.33%) of the hyperthyroidism group and in 23 cases(accounting for 30.67%) of the control group, with statistically significant differences(P<0.05). The ECG changes mainly concentrated on ST segments and T waves. In the aspect of heart rate, the hyperthyroidism group was significantly faster than the control group, with (77.72±12.98) times/min in the former and (71.29±10.14) times/min in the latter, and the differences were statistically significant.In the hyperthyroidism group, the incidence of abnormal ECG of females(61.70%) was obviously higher than that of males(32.14%), with statistically significant differences. Compared with the control group, there were decreased QT interval, prolonged QTc interval and increased amplitude of P wave in the hyperthyroidism group, and the differences were statistically significant.ConclusionThe incidence of abnormal ECG in patients with hyperthyroidism is higher than that in normal group. ECG can provide some reference value for the diagnosis of hyperthyroidism.
