摘要
目的:研究冠心病患者的心功能和肺动脉压(PAP)、心电指标之间的关系。方法:选择2009年10月—2010年5月在我院住院的冠心病患者113例,按照NYHA分级分为A组(Ⅰ、Ⅱ级)、B组(Ⅲ级)、C组(Ⅳ级),比较3组之间的PAP、P波离散度(Pd)、QT间期(QT)、QT离散度(QTd)、T波峰-末间期(Tp-e)和经纠正后的QT(QTc)、QTd(QTcd)、Tp-e(Tp-e/e/RR^(1/2))之间的差异。结果:3组之间的PAP、Pd、QT、QTc、QTd、QTcd、Tp-e、Tp-e/e/RR^(1/2)比较差异有统计学意义(P<0.05),并且随着心功能的恶化(B组对A组,C组对B组),PAP逐渐升高,Pd、QT、QTc、QTd、QTcd、Tp-e、Tp-e/e/RR^(1/2)逐渐增加,差异具有统计学意义(P<0.05)。结论:冠心病患者随着心功能的恶化,PAP有升高的趋势,Pd、QT、QTc、QTd、QTcd、Tp-e、Tp-e/e/RR^(1/2)有增加的趋势,发生房颤和恶性心律失常的风险增加。
Objective: To investigate the relationship between the heart function and pulmonary arterial pressure (PAP), electrocardiogram(ECG)indices in patients with coronary heart disease (CHD). Methods: According to NYHA classification, 113 hospitalized patients were classified into A group (Ⅰ and Ⅱ), B group (Ⅲ) and C group (Ⅳ). The values of PAP, P dispersion (Pd), QT interval(QT), QT dispersion (QTd), T peak-tend interval(Tp-e) and corrected QT (QTc), corrected QTd (QTcd), corrected Tp-e (Tp-e/√RR) were compared between three groups. Results: There were significant differences in PAP, Pd, QT, QTc, QTd, QTcd, Tp-e and Tp-e/√RR between three groups (P〈0.05). The values of PAP,Pd, QT,QTc,QTd, QTcd, Tp-e and Tp-e/√RR were gradually increased with the deterioration of heart function in B group vs A group, C group vs B group. The differences were significant (P〈0.05). Conclusion: The pulmonary arterial pressure and all of the ECG indices, including Pd, QT, QTc, QTd, QTcd, Tp-e and Tp-e/√RR were enhanced with the deterioration of heart function in CHD patients. Patients with heart failure are more likely to suffer from atrial fibrillation and malignant cardiac arrhythmia.
