  • 采用Barkley模型研究了径向电脉冲对可激发介质中螺旋波脱钉的影响. 数值模拟结果表明, 径向电脉冲可成功地帮助螺旋波从缺陷上脱钉. 单次径向电脉冲可以在弱激发区域成功地帮助螺旋波从缺陷上脱钉, 但在激发性强的介质中则不能帮助螺旋波实现脱钉. 单次径向电脉冲的脱钉参数空间大于均匀电场和抗心动过速起搏方法的脱钉参数空间. 多次径向电脉冲可在可激发介质中整个螺旋波存在的参数空间脱钉. 对比其他使用电场脱钉的方法, 采用径向电脉冲方法脱钉具有电场强度低、成功率高和脱钉参数空间大等优点. 并且采用本方法脱钉时, 其成功率对螺旋波在缺陷上的钉扎相位不敏感. 我们希望本方法能为临床中治疗相关心脏疾病提供一种新思路.
    In this paper, the process of unpinning spiral waves from obstacles with pulses of radial electrical field (PREF) in excitable medium is studied by using Barkley model. We use a radial electrical field to simulate the field of an needle electrode placed in the middle of a round obstacle. Numerical results show that the PREF can separate spiral waves from obstacles effectively. With a single pulse of radial electrical field (SPREF), spiral waves can be unpinned from an obstacle effectively in a weakly excitable medium, but it cannot be unpinned in a strongly excitable medium. The unpinning parameter space of an SPREF is larger than that of a uniform electric field or anti-tachycardia pacing. Multiple pulses of radial electrical field (MPREF) is effective for unpinning in the entire parameter space where spiral waves exist. Compared with other methods to unpin spiral waves, the PREF method has the advantages of low electric field magnitude, high success rate, and large application range in the parameter space. And unlike other methods, the PREF has a success rate insensitive to the phase of the spiral wave on the obstacle. We hope that this method will provide a new idea for clinical treatment for related cardiac diseases.
