植入型心律转复除颤器的右室除颤电极导线通常放置于右室心尖部,但近来研究显示长期右室心尖部起搏会导致心脏收缩和舒张功能下降,另外,当右室心尖部起搏阈值和/或除颤阈值较高时,需改变除颤电极导线的放置位置,以达到最佳的治疗效果。相对于右室心尖部而言,右室流出道放置除颤电极导线有一定的优势。现对右室流出道放置除颤电极导线的相关问题做一简要的综述。 Right ventricular apical defibrillator lead electrodes are usually placed in the right ventricular apex, but recent studies have shown that long-term right ventricular apex pacing lead to decreased cardiac systolic and diastolic function, in addition, when the right ventricular apex When the pacing threshold and / or the defibrillation threshold are higher, change the defibrillation electrode lead position to achieve the best therapeutic effect. Relative to the right ventricular apex, right ventricular outflow tract placement defibrillation electrode lead has some advantages. Now right ventricular outflow defibrillation electrode placed on the lead wire issues a brief review.
