问题 单项选择题

男性,64岁,无任何诱因突感上腹剧烈疼痛,持续1小时不缓解,伴恶心、呕吐,急诊心电图示Ⅱ、Ⅲ、aVF导联 ST段弓背向上抬高。其原因可能是

A.急性6旦囊炎
B.急性胰腺炎
C.胃痉挛
D.急性下壁心肌梗死
E.急性前壁心肌梗死

答案

参考答案:D

解析:此老年男性病人,突然无诱因上腹剧烈疼痛1小时不缓解,这是不典型的心肌梗死疼痛的放射部位,心电图改变提示急性下壁心肌梗死,恶心和呕吐是心肌梗死的胃肠道症状,多见于下壁心梗,所以此病人最可能是患急性下壁心肌梗死,若为前壁心梗,心电图改变应在胸前导联,其余三个诊断均不像。

A 2-year-od boy is being described as a hero after using Face Time to save his mother after she was badly hurt.

According to a report from KGUN, Laura was trying to stop a fight between two dogs when one of the dogs bit(咬) part of her middle finger almost completely off.

Laura tried to call 911 herself, but she said her hands were too badly hurt to make the call. “ I asked my daughters to call 911, and they’re four, and they were quite afraid to even touch the phone, because it was covered in my blood(血),” Laura told KGUN.

The mother continued to lose a lot of blood and thought she would go into a deep sleep—until her 2-year-old son Bentley came up with a dishcloth from the kitchen. After cleaning some of the bold off his mother’s iPhone, Bentley continued to use Face Time to call Laura’s friend Connie.

“All I could see was his little forehead. I said ‘Hi Bentley’ and it was quiet for a little bit. Then I heard Laura shouting,” Connie told KGUN.

Connie then called 911, and Bentley unlocked the door to let firefighters into the house.

Laura told KGUN she is very thankful for her little hero and has since taught all of her children how to call 911.
