食道调搏试验具有简便、安全、实用、便于重复等优点,所以近年来这项工作在我国得到广泛的开展。但也有很多不足之处需要改进。目前国内都是用单导联心电图机作为食道调搏试验的记录工具,记录导联选用标准Ⅱ导联,心房活动产生的A波经常淹没在刺激伪迹中,给试验结果的分析带来了很大局限。本院从1984年8月以来改用了V~1导联作为监察和记录导联,结果十分满意,特此向同道介绍。一、原理和图例食道调搏是一种双极电刺激技术,刺激导管远端接刺激脉冲负极,近端接刺激脉冲
Esophageal pacing test is simple, safe, practical, easy to repeat, etc., so in recent years this work has been widely carried out in our country. But there are also many shortcomings need to be improved. At present, the single-lead electrocardiogram machine is used as a recording tool for esophageal pacing test, recording lead selection standard Ⅱ lead, A-wave generated by atrial activity is often submerged in stimulation artifacts to the analysis of the test results Very limited. Since August 1984, this court switched to V-1 lead as a monitoring and recording lead, the result was very satisfactory. We hereby introduce to you. First, the principle and legend Esophageal pacing is a bipolar electrical stimulation technology to stimulate the distal end of the catheter to stimulate the pulse negative, the proximal stimulation pulse
