患者女性,58岁,反复发作胸痛1周,每次持续数分钟自行缓解。患者胸痛时的心电图见图5-30:

应考虑为()

A.急性前壁心肌梗死

B.急性心包炎

C.急性心肌缺血

D.早期复极综合征

E.急性下壁心肌梗死

答案

参考答案:C

解析:

窦性心律,急性心肌缺血,肢体导联低电压解析:心电图显示窦性频率86次/分,PR间期0.13秒。肢体导联中QRS波振幅<0.5mV,Ⅰ、aVL导联ST段抬高伴Ⅱ、Ⅲ、aVF导联ST段对应性下移;V1~V5导联ST段明显抬高,其中V4~V5导联ST段抬高达0.6~1.0mV.呈单向曲线;V1~V3导联T波直立,V2、V3导联T波高尖。此图结合病史特点,应考虑为变异型心绞痛。如ST段持续性抬高超过20分钟,提示可能发生急性心肌梗死。

At exactly eleven Sir Percival knocked and entered, with anxiety and worry in every line of his face. This meeting would decide his future life, and he obviously knew it.

“You may wonder, Sir Percival,” said Laura calmly, “if I am going to ask to be released(免除)from my promise to marry you. I am not going to ask this. I respect my father’s wishes too much.”

His face relaxed a little, but one of his feet kept beating the carpet.

“No, if we are going to withdraw(退出)from our planned marriage, it will be because of your wish, not mine. ”

“Mine?” he said in great surprise. “What reason could I have for withdrawing?”

“A reason that is very hard to tell you,” she answered. “There is a change in me.”

His face went so pale that even his lips lost their color. He turned his head to one side.

“What change?” he asked, trying to appear calm.

“When the promise was made two years ago”, she said, “my love did not belong to anyone. Will you forgive me, Sir Percival, if I tell you that it now belongs to another person?”

“I wish you to understand”, Laura continued, “that I will never see this person again, and that if you leave me, you only allow me to remain a single woman for the rest of my life. All I ask is that you forgive me and keep my secret.”

“I will do both those things,” he said. Then he looked at Laura, as if he was waiting to hear more.

“I think I have said enough to give you reason to withdraw from our marriage,” she added quietly.

“No. You have said enough to make it the dearest wish of my life to marry you,” he said.
