心房颤动(简称房颤)是临床上常见的心律失常之一,80岁以上的人群发病率接近10%[1]。房颤导致的脑卒中的死亡率也显著高于非房颤者[2]。因此有效地治疗房颤十分重要。由于药物治疗效果有限,且有较多副作用[3],房颤的射频消融治疗成为重要的治疗方法之一。多层螺旋CT(MSCT)能在术
Atrial fibrillation (atrial fibrillation) is one of the common clinical arrhythmias, with a prevalence of nearly 10% in people over 80 years of age [1]. Atrial fibrillation-induced stroke mortality was also significantly higher than non-AF [2]. Therefore, effective treatment of atrial fibrillation is very important. Due to the limited effect of medical treatment and more side effects [3], radiofrequency ablation of atrial fibrillation has become an important treatment. Multi-slice spiral CT (MSCT) in surgery
