86例肺结核患者顺钟向转位心电图分析

Analysis of clockwise rotation electrocardiograms of 86 patients with pulmonary tuberculosis

目的探讨顺钟向转位心电图对肺结核患者右心室肥大的诊断价值。方法对我院收治的86例顺钟向转位心电图的肺结核患者进行超声心动图筛查,并将其分为右心室肥大组和非右心室肥大组。除顺钟向转位外,比较两组患者心电图的其他改变之间的差异。结果在86例患者中,超声心动图证实为右心室肥大者40例(46.5%),非右心室肥大者46例(53.5%)。与非右心室肥大组患者相比,右心室肥大组患者的心电图的其他伴随改变,如电轴右偏、窦性心动过速、ST-T改变、P波高尖增多,且差异具有统计学意义(P均<0.05)。结论肺结核患者顺钟向转位心电图对右心室肥大有一定诊断价值,尤其是伴有电轴右偏、窦性心动过速、ST-T改变、P波高尖时应高度怀疑右心室肥大。

Objective To explore the diagnostic value of clockwise rotation electrocardiogram（ECG） for right ventricular hypertrophy in patients with pulmonary tuberculosis. Methods Echocardiogram was performed on patients with pulmonary tuberculosis and clockwise rotation ECG so as to divide them into right-ventricular-hypertrophy group and non-right-ventricular-hypertrophy group. Besides clockwise rotation, compare the differences of other ECG changes between the two groups.Results Among 86 cases, it indicated by echocardiogram that 40 cases（46.5%） fell in the right-ventricular-hypertrophy group while 46（53.5%） in the other. Compared with patients in non-right-ventricular-hypertrophy group, the other group showed higher incidence rate of other concomitant ECG changes, such as right axis deviation, nodal tachycardia, ST-T change as well as high and sharp P wave. In addition, the differences possessed statistical significance（P0.05）. Conclusion Clockwise rotation ECG of patients with pulmonary tuberculosis have some value in the diagnosis of right ventricular hypertrophy. It strongly indicates the chance of right ventricular hypertrophy, especially when right axis deviation, nodal tachycardia, ST-T change as well as high and sharp P wave appear.
