经静脉放置电极导管发放电刺激对心脏停搏、严重窦缓和快速心律失常都是一种有效的治疗方法,但由于其具有创伤性和一定程度的危险性且对操作人员专业技术要求较高而限制了其广泛应用。然而某些快速性心律失常当无创性治疗方法如抗心律失常药物和电复律无效或有禁忌时,抗心动过速电刺激便成为必须选择的手段。经食管电刺激是一种简单、安全的无创性治疗方法,但由于技术方面的原因临床上也未能广泛应用。其主要原因有以下几点:①安放食管电极给病人带来不适;②电刺激引起
Intravenous catheter placement of electrical stimulation on cardiac arrest, severe sinus arrhythmia and tachyarrhythmias are an effective treatment, but because of its traumatic and a certain degree of risk and the professional and technical requirements of the operator and higher Limit its wide application. However, some tachyarrhythmia anti-tachycardia electrical stimulation has become a must have when non-invasive treatment methods such as antiarrhythmic drugs and electrical cardioversion ineffective or contraindicated. Esophageal electrical stimulation is a simple, safe and non-invasive treatment, but due to technical reasons, it has not been widely used clinically. The main reasons for the following: ① placed esophageal electrode to the patient discomfort; ② caused by electrical stimulation
