女性,38岁,患者曾有甲状腺功能亢进,内科治疗5年后症状消失。近几日因与丈夫吵架,夜不能寐。昨日起心慌、胸闷、不安。体检见心率160次/分,心电图显示窦性心律不齐,心肌缺血。 若该患者还有支气管哮喘,应该改用哪个药物()

A.美托洛尔

B.卡维地洛

C.拉贝洛尔

D.利多卡因

E.普萘洛尔

答案

参考答案:A

解析:

β受体阻断剂可用于窦性心动过速,尤其适用于伴焦虑者。

可以选用选择性β受体阻断剂避免支气管哮喘加重。

长期应用β受体阻断剂突然停药可发生反跳现象,称为撤药综合症。表现为高血压、心律失常和心绞痛加重,与长期β受体敏感性上调有关。

I grew depressed (沮丧的), even as my husband Charlie’s career skyrocketed. He was a NASA astronaut. I was excited for him when he began training to go to the moon, and I involved (潜心于) myself with the flight as much as possible, but I was really looking forward to it being over. Inside I was hoping that once he got this goal behind him, he would put me first.

But he didn’t. He still had that workaholic(工作狂) drive. He was still following a list of goals which I was still down near the bottom of. I considered breaking up but I wondered if any man could love me the way I wanted to be loved. Was there even such a thing as the perfect marriage? I didn’t wish it anymore. However, in his eyes, our marriage certainly hadn’t delivered any satisfaction, so within several years we were heading full-speed toward breaking up.

I began to look for other things to satisfy me. I tried a career. I tried church work. I helped the needy. Nothing worked. I even tried drugs, but they didn’t work either. I thought, maybe there was no purpose in life. Didn’t that seem strange? I was married to a famous man, had a nice home and healthy children, plenty of money, yet I had no hope.

I also discovered God, and I believed He wanted to change me. I found He wanted me to forgive Charlie, so I tried that, although I felt it was impossible. But over a two-month period, God freed me of my anger and helped me love Charlie unconditionally.
