药物和其它抗心律失常措施对缓解绝大多数患者的心律失常十分有效。但对部份病人可能无效,对这些病人,以前只能借助于手术治疗。近年来,由于心内导管电击疗法的开展,使某些严重心律失常病人可以免除手术而治愈。目前应用于临床的心内电击术有:直流电击,激光及高频电流电凝术等。以下仅就心内导管直流电击术作一概述。 电击切除术的目的是消除异位兴奋灶,打断折返环或阻断房室结,达到控制心律失常的目的。 方法:将一普通除颤器与心内电极导管
Drugs and other anti-arrhythmic measures are effective in relieving cardiac arrhythmias in the vast majority of patients. However, it may not be effective for some patients. In the past, these patients could only be treated with surgery. In recent years, due to the development of intracardiac catheterization therapy, some serious arrhythmia patients can be cured without surgery. Currently used in clinical cardiac electrosurgery are: DC shock, laser and high-frequency current coagulation and so on. The following is only an overview of intracardiac catheterization. The purpose of shock resection is to eliminate ectopic excitement stove, interrupt the reentry ring or block the atrioventricular node, to achieve the purpose of controlling arrhythmia. Methods: An ordinary defibrillator and intracardiac lead
