试题解析

①强心苷为具有选择性强心作用的药物，临床上主要用以治疗心功能不全和某些心律失常，尤其是室上性心律失常。②奎尼丁为膜抑制性抗心律失常药，主要用于慢性心房纤颤和心房扑动，使其转为窦性心率。③维拉帕米属钙拮抗药，可用于抗心律失常及抗心绞痛，对于阵发性室上性心动过速最有效；对房室交界区心动过速疗效也很好；也可用于心房颤动、心房扑动和房性早搏。④普萘洛尔为P受体阻断剂，用于房性及室性早搏，窦性及室上性心动过速、心绞痛、急性心梗、高血压等；对慢性心房颤动和扑动，如果用洋地黄疗效不佳，加用本品常可减慢心室率。故不选A、B、D、E。⑤利多卡因为酰胺类局麻药及抗心律失常药，可阻断钠通道，对各种室性心律失常疗效显著，对急性心肌梗死患者的室性早搏、室性心动过速及心室颤动，可作为首选药，对房颤无效
