A.心房兴奋过程

B.心室兴奋过程

C.心室复极化过程

D.心室开始兴奋到心房兴奋过程之间的时间

E.心房开始兴奋到心室开始兴奋之间的时间

答案

参考答案:E

解析:正常心电图包括P波、QRS波群和T波。P波是一个小波,P波终点说明左、右心房已全部兴奋;QRS波群反映两心室均已全部兴奋;P-R间期反映心房开始兴奋到心室开始兴奋所经历的时间;Q-T间期反映心室开始兴奋到心室全部复极化结束所需的时间。因此,正常心电图P-R间期反映心房开始兴奋到心室开始兴奋之间的时间。故答案选择E。

Love, success, happiness, family and freedom——how important are these values to you? Here is one interview which explores the fundamental questions in life.

Question: Could you introduce yourself first?

Answer: My name is Misbah, 27 years old. I was born in a war-torn area. Right now I’m a web designer.

Q: What are your great memories?

A: My parents used to take us to hunt birds, climb trees, and play in the fields. For me it was like a holiday because we were going to have fun all day long. Those are my great memories.

Q: Does your childhood mean a lot to you?

A: Yes. As life was very hard, I used to work to help bring money in for the family. I spent my childhood working, with responsibilities beyond my age. However, it taught me to deal with problems all alone. I learnt to be independent.

Q: What changes would you like to make in your life?

A: If I could change something in my life, I’d change it so that my childhood could have taken place in another area. I would have loved to live with my family in freedom. Who cares whether we have much money, or whether we have a beautiful house? It doesn’t matter as long as I can live with my family and we are safe.

Q: How do you get along with your parents?

A: My parents supported me until I came of age. I want to give back what I’ve got. That’s our way. But I am working in another city. My only contact with my parents now is through the phone, but I hate using it. It filters(过滤)out your emotion and leaves your voice only. My deepest feelings should be passed through sight, hearing and touch.
