摘要 室性心律失常(VA)患者常有心功能不全,而心功能不全患者易发生VA,故检测与评价VA患者的心功能状态具有重要意义。目前用于评价VA患者心功能的方法主要有①根据临床表现的NYHA心功能分级法及Kil-lip分级法;②根据客观检测的体表心电图、胸部X线、超声心动图、核素灌注扫描、磁共振显像、计算机断层扫描、放射性核素心室造影及有创性心导管检测;③根据运动负荷的踏车或活动平板试验以及6min步行试验;④根据血清生化指标的B型脑钠肽检测等。其中最常用的方法是NYHA心功能分级与超声心动图;最常用的指标是反映左室收缩功能的射血分数。评价VA患者心功能有助于①了解VA的基础病因;②预测VA发生的风险;③指导VA的临床治疗;④把握VA患者接受埋藏式心脏转复除颤器治疗的适应证。
