Medical-technical characteristics of electrodes for epicardial mapping are examined. Most electrodes are bipolar. The differences between them lies either in the contact configuration or in the fixation mode. The dependence of biosignal amplitude and shape on the contact orientation with respect to the direction of excitation spread is described. Free from this dependence are electrodes with a central point contact and a ring contact through the periphery Clinging and screw-in electrodes are useful for long-term monitoring while stick and suction electrodes are recommended for short-term recording from multiple sites. Ring electrodes put on a finger are advantageous in hardly accessible zones.
研究了用于心外膜标测的电极的医学技术特性。大多数电极是双极的。它们之间的差异在于接触配置或固定方式。描述了生物信号幅度和形状与相对于兴奋传播方向的接触方向的依赖性。具有中心点接触和通过周边的环形接触的电极不受这种依赖性的影响。粘贴式和旋入式电极适用于长期监测，而棒状和抽吸式电极推荐用于多部位的短期记录。戴在手指上的环形电极在难以触及的区域具有优势。
