WFB—Ⅱ型体外反搏装置,在使用中如果偶尔出现一两次漏触发,可能是病人心电太弱“R”波偏低,不能有效地触发充排气电路所致。若在使用中开始尚好,以后漏触发现象从偶尔出现发展到频繁出现,则需对装置进行详细检查,排除故障。现将我们排除这类故障的经过介绍如下。开机后先将心模开关置于“模拟”位置, WFB-Ⅱ EECP device, if in use occasionally one or two leak trigger, the patient may be too weak “R” wave is too low, can not effectively trigger the charge and discharge circuit. If the beginning is still good in use, after the leakage trigger phenomenon occurs from time to time to appear frequently, you need to conduct a detailed inspection of the device to troubleshoot. Now we exclude the failure of these are described below. After switching on the heart mode switch placed in the “analog” position,
