由于经食道对心室电刺激脉冲(80—90V)比经食道对心房电刺激脉冲高,起搏节律又不稳定,病人有不适感,所以这种方法一直未能广泛使用。本研究克服了这些缺点。适距离的原则而获得。电刺激器加接一个供放大、增宽脉冲用的附加器。附加器的阴极接第1触点,阳极以3个方案分别接:1.第2触点,2.接短路在一起的2、3、4触点,3.接短路在一起的2、3、4、5、6触点。短路接在一起是为增大阳极接触面积。为了在食道得到最大心室电位(1.5—3mV),阴极引进的最适深度因身高而异,变化在28—50cm之间。阴极(第1触点)离贲门上距离随个体变异不大,自2.5—5cm
This method has not been widely used because the transesophageal electrical ventricular electrical stimulation pulse (80-90V) is higher than the transesophageal atrial electrical stimulation pulse, the paced pace is not stable and the patient has discomfort. This study overcomes these shortcomings. Obtained from the principle of distance. Add a stimulator for amplification, widening pulse with the addendum. The cathode of the adjuster is connected with the first contact, and the anode is connected with three solutions respectively: 1. second contact, 2. connect the short circuit with the 2,3,4 contacts, 3. connect the short circuit together with 2,3 , 4, 5, 6 contacts. Short circuit together is to increase the anode contact area. In order to get the maximum ventricular potential in the esophagus (1.5-3mV), the optimum depth of cathode introduction varies with height and varies between 28-50cm. Cathode (first contact) from the cardia on the distance variation with the individual is not, since 2.5-5cm
