QRS时限、Tp-Tec、QTc在慢性心力衰竭患者心电图检查中的应用价值

Application value of QRS time limit, Tp-Tec and QTc in electrocardiogram examination for patients with chronic heart failure

目的探讨QRS时限、Tp-Tec、QTc在慢性心力衰竭(CHF)患者心电图检查中的应用价值。方法选取2016年8月至2018年1月我院收治的60例CHF患者为研究对象,根据是否合并室性心律失常将其分为A组(24例,合并室性心律失常)和B组(36例,未合并室性心律失常),另选取同期入院体检的健康人员30名作为C组。所选对象均在入院后接受心电图检查,比较三组受检者入院时的QRS时限、Tp-Tec、QTc等心电图参数水平;A、B组患者均接受3个月治疗,比较A、B组患者治疗后的QRS时限、Tp-Tec、QTC减少值及疗效。结果 A、B组患者的QRS时限、Tp-Tec、QTc均显著长于C组,差异均具有统计学意义(P<0.05);A组患者的QRS时限、Tp-Tec均显著长于B组,差异均具有统计学意义(P<0.05)。治疗后,A组患者的QRS时限、Tp-Tec、QTc减少值均显著大于B组,差异均具有统计学意义(P<0.05);A组患者的治疗总有效率显著高于B组,差异具有统计学意义(P<0.05)。结论心电图检查中的QRS时限、Tp-Tec、QTc等参数水平可提示CHF的发生情况和病情严重程度,而上述参数的变化情况也能为临床疗效的评价和预测提供一定的参考依据,值得临床借鉴。

Objective To explore the application value of QRS time limit, Tp-Tec and QTc in electrocardiogram examination for patients with chronic heart failure (CHF). Methods A total of 60 cases of patients with CHF treated in our hospital from August 2016 to January 2018 were selected as the study objects and divided into group A (24 cases, with ventricular arrhythmias) and group B (36 cases, without ventricular arrhythmias) according to whether they had ventricular arrhythmias. Another 30 healthy persons who admitted in hospital for physical examination at the same time were selected as group C. All the study objects were examined by electrocardiogram after admission, and the QRS time limit, Tp-Tec and QTc were compared among the three groups. The QRS time limit, Tp-Tec, QTC reduction value and curative effect of the groups A and B after treatment were compared. Results The QRS time limit, Tp-Tec and QTc in the groups A and B were significantly longer than those in the group C, and the differences were statistically significant (P<0.05). The QRS time limit and Tp-Tec in the group A were significantly longer than those in the group B, and the differences were statistically significant (P<0.05). After treatment, the QRS time limit, Tp-Tec and QTc reduction value in the group A were significantly greater than those in the group B, the differences were statistically significant (P<0.05);the total effective rate of treatment in the group A was significantly higher than that in the group B, the differences were statistically significant (P<0.05). Conclusion The QRS time limit, Tp-Tec and QTc in electrocardiogra examination can indicate the occurrence and severity of CHF, and the changes of which can also provide some references for the evaluation and prediction of clinical efficacy and is worthy of clinical reference.
