The authors suggest a modified method for recording bronchial ECG leads by means for recording bronchial ECG leads by means of a catheter-electrode of their design which is introduced through the inner canal of an optic broncho-fibroscope under local anesthesia. The electrode is adjusted in the right inferior bronchus on a level with the 7th segment. The bronchial ECG leads were analyzed in 122 persons (in 25 healthy individuals and 97 patients with chronic respiratory insufficiency). A conclusion is drawn that bronchial ECG leads make it possible to diagnose early involvement of the right atrium in the pathological process relatively often. In destructive changes in the lungs, the degree of right atrial overloading increases. As compared to ordinary orthogonal leads, bronchial ECG leads increase the efficacy of cor pulmonate diagnosis significantly.
作者们提出了一种改进方法，通过他们设计的导管电极来记录支气管心电图导联，该导管电极在局部麻醉下通过光学支气管纤维镜的内通道插入。电极在右下支气管与第7节段同一水平处进行调整。对122人（25名健康个体和97名慢性呼吸功能不全患者）的支气管心电图导联进行了分析。得出的结论是，支气管心电图导联能够相对频繁地诊断出右心房较早参与病理过程。在肺部出现破坏性改变时，右心房超负荷程度增加。与普通正交导联相比，支气管心电图导联显著提高了肺心病诊断的效能。
