心电指标改变和心血池造影定量分析在肺心病中的临床应用

Electrocardiographic features and quantitative analysis of blood pool imagings in the clinics of pulmonary heart disease

目的探讨在平衡法心血池造影和心电检测各指标的改变,以评价肺心病患者的心功能。方法对38例肺心病失代偿期(包括急性加重期)患者和18例肺心病代偿期(包括缓解期)患者进行平衡法心血池造影和心电检测。结果肺心病患者随着病情的加重,STⅡ,Ⅲ,aVF压低可出现肺型P波、紊乱性房性心动过速、极度顺钟向转位;高峰充盈率和射血分数均逐渐下降,高峰充盈时间改变不明显。结论心室的泵功能与肺心病本身病情的轻重有密切的关系,应用心电检测各指标结合核素平衡法心血池造影,可用于早期诊断肺心病和评价肺心病患者的心功能。

Objective To evaluate the function of left ventricle during acute exacerbation of chronic pulmonary heart disease(CPHD) with electrocardiography(ECG) and equilibrium blood pool imaging(EBPI).Methods A comparison of the ECG and EBPI data between 38 patients with acute exacerbation of CPHD and 18 patients with compensation phase of CPHD was made Results Along with depravation of CPHD, the P pulmonary, QRS wave right axis deviation or chest lead clockwise rotation, sinus tachycardia, limb lead low voltage, ST segment depressed in leadⅡ,Ⅲ,aVF,atrial and ventricular arrhythmias, etc,occurred one after another. The peak filling rate(PFR) and peak ejection rate(PER) were gradually to lower;EBPI showed no obvious change in peak filling time( PFT). Conclusion Ventricular bumping function has a close relation with the CPHD condition,using ECG and EBPI may early diagnose pulmonary heart disease and evaluate the heart function.
