ECG和MGBP在肺心病中的应用

The clinical application of ECG and MGBP in patients with pulmonary heart disease

目的:探讨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,于STⅡ、Ⅲ、avF导联可出现肺型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 ventricular in ECG and MGBP with acute exacerbation of chronic pulmonary heart disease(CPHD). Methods:To make a comparison between the ECG and MGBP of 38 patients with acute exacerbation of CPHD and 18 patients with recovery of CPHD. 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, et al. One by one in order to appear. The peak filling rate(PFR) and peak ejection rate(PER) gradually to lower. No obvious difference in MGBP in the peak filling time( PFT). Conclusion:There is close relation in function of pump on ventricular with CPHD. Applying ECG and MGBP can diagnose and evaluate the function of pump of left ventricular with CPHD earlier.
