图2。贴在胶带上的电极的照片。在电极1和2之间保持良好的分离是很重要的。这种电极配置用于通过观察Z（电极2和3之间的总阻抗）来获得1)心功能数据和2)胸腔内总液体的变化。测量Z值已被发现是一种非常敏感的指标，可指示诸如肺水肿、肺充血和胸腔积液等情况的发展或逆转。胸阻抗测量用电极膏。该电极重量轻，舒适，具有足够的电特性，可用于经胸和肢体阻抗测量。胶带电极放置在受试者上，如图2所示。电极很容易通过连接病人的电缆上的鳄鱼夹连接到阻抗心电图仪上。
FIGURE 2. A photograph of the tape-on electrodes in place. It is important to maintain good separation between electrodcs 1 and 2. This electrode configuration is used for obtaining 1) cardiac function data and 2) changes in total fluid in the chest by observing Z,(the total impedance between electrodes 2 and 3). The Z, measurement has been found to be a very sensitive indicator of the development or reversal of such conditions as pulmonary edema, pulmonary congestion, and pleural effusion. electrode paste for thoracic impedance measurements. The electrode is lightweight and comfortable and possesses adequate electrical characteristics for transthoracic and limb impedance measurements. The tape-on electrodes are positioned on the subject as shown in FIGURE 2. The electrodes are easily attached to the impedance cardiograph by means of alligator clips on the patient-connecting cables.
