问题 单项选择题 A1/A2型题

对于尖端扭转型室性心动过速的治疗,下列哪一项是错误的()。

A.直流电360J复律

B.停用洋地黄、胺碘酮

C.经深静脉补钾、补镁

D.予异丙肾上腺素提升心率到90~100bpm

E.意识丧失者需心外按压以维持心泵功能

答案

参考答案:A

解析:尖端扭转型室性心动过速不宜采用直流电复律。异丙肾上腺素能提高基础心率,使心室复极一致,缩短Q-T间期。低钾、低镁可使Q-T间期延长,U波明显,诱发尖端扭转型室性心动过速。

Different people use different languages. We Chinese speak Chinese, and, most of us are learning a foreign language. But there is another kind of language we need to know --- the language of the body.

All over the world, people “talk with their hand, with their heads and with their eyes.” When Japanese people meet, they bow. When Indians meet, they put their hands together. What do American and British do? Americans are more imformal(不拘小节的) than the British. They like to be friendly. They use first names, they ask questions and they talk easily about themselves. When they sit down, they like to relax in their chairs and make themselves comfortable. British people are more reserved(保守的). They take more time to make friends. They like to know you before they ask your name.

When British or American people meet someone for the first time, they shake hands. They do not usually shake hands with people they know well. Women sometimes kiss their women friends, and men kiss women friends (on one cheek only). When a man meets a man, he just smiles, and says, “Hello.” Men do not kiss each other, or hold hands. Even fathers and sons do not often kiss each other.
