Abstract

We set out to determine in a prospective fashion the characteristics of energy delivery related to defibrillation in a population of patients receiving the AICD. Specifically, we examined the characteristics of the delivered current, transmyocardial voltage, and transmyocardial impedance. Secondly, we determined the relationship between the energy delivered, the impedance encountered and the defibrillation threshold. Since the AICD will deliver a succession of shocks if the initial shock does not cardiovert, the effects of consecutive shocks at different energy levels on the transmyocardial impedance were also assessed.

摘要

我们着手以前瞻性方式确定接受植入式心律转复除颤器（AICD）的患者群体中与除颤相关的能量传递特征。具体而言，我们检查了输送电流、跨心肌电压和跨心肌阻抗的特征。其次，我们确定了输送的能量、遇到的阻抗与除颤阈值之间的关系。由于如果初始电击不能使心脏复律，AICD会连续发出电击，因此还评估了不同能量水平的连续电击对跨心肌阻抗的影响。
