心电图V1导联P波终末电势与心力衰竭患者心功能分级及并发心律失常相关性研究

Correlation between P-wave terminal potential(Ptfv1) in electrocardiogram V1 lead and cardiac function grading and concurrent arrhythmia in patients with heart failure(HF)

目的探讨心电图V1导联P波终末电势(Ptfv1)与心力衰竭(HF)患者心功能分级及并发心律失常的关系。方法将我院2016年1月~2017年1月收治的200例心力衰竭患者作为本次研究观察组,另选取200例同期于我院进行健康体检的正常健康人群为对照组,两组均行常规心电图检查,并测量两组受检对象Ptfv1。对两组受检对象行24 h动态心电监护,计算受检人群心律失常情况。结果不同心功能分级心力衰竭患者Ptfv1明显高于对照组,且随着心功能分级的增加,患者Ptfv1值也逐渐增加,差异有统计学意义(P<0.05)。相同心功能分级者在不同Ptfv1值区间发生心律失常率比较,差异有统计学意义(P<0.05);随着Ptfv1值的增加,心律失常患病率呈升高趋势,差异有统计学意义(P<0.05)。相同Ptfv1值区域间,不同心功能分级者心律失常发生率相比较,差异无统计学意义(P>0.05)。结论 Ptfv1值随着心力衰竭患者心功能分级的增加而增大,且相同心功能分级者,随着Ptfv1值的增大,其发生心律失常几率越高,因此临床可通过监测心电图V1导联P波终末电势(Ptfv1)来预测患者预后,同时为临床疾病治疗提供有力依据。

Objective To investigate the relationship between P wave terminal potential(Ptfv1) in ECG V1 lead and cardiac function grading and arrhythmia in patients with heart failure(HF). Methods 200 cases of heart failure admitted to our hospital from January 2016 to January 2017 were used as the observation group. Another 200 normal healthy people who were in our hospital for health examination at the same time were selected as the control group. Both groups underwent conventional electrocardiogram examination. And the Ptfv1 of two groups was measured. The two groups of subjects underwent 24 h dynamic ECG monitoring. The arrhythmia of the subjects was calculated. Results Ptfv1 was significantly higher in heart failure patients with different cardiac function classification than that in the control group, and the Ptfv1 value increased gradually with the increase of cardiac function classification, The difference was statistically significant(P<0.05). The arrhythmia rate in the different Ptfv1 values in those with same cardiac function classification was statistically significant(P<0.05). The prevalence of arrhythmia increased with the increase of Ptfv1 value, and the difference was statistically significant(P<0.05). There was no significant difference in the incidence of arrhythmia between the same Ptfv1 values in different cardiac function classifications(P>0.05). Conclusion The Ptfv1 value increases with the increase of cardiac function grading in patients with heart failure. And in those with the same heart function grading, with the increase of Ptfv1 value, the higher the incidence of arrhythmia. Therefore, the clinical prognosis can be predicted by monitoring the P wave terminal potential(Ptfv1) in the V1 lead of the electrocardiogram, while providing a strong basis for clinical disease treatment.
