简介：患者女性,64岁,因活动后心慌。心前区不适3年．加重伴心前区疼痛1天就诊。查体：患者痛苦面容．皮肤湿冷；体温35．50℃；心率160次／分；呼吸28次／分；血压80／60mmHg。立即检查心电图示房室折返性心动过速。随即在心电监测下做左侧颈脉窦按摩，按摩约3s后，即出现1．34s的窦性停搏，又在一次P—R间期缩短的室上性激动后出现-12．38s的窦性停搏．当停搏8．86s时，患者出现两眼上翻，面色苍白．肌张力增强，立即心前区叩击一次并胸外心脏按压，3．5s后相继出现2．4s的室性心动过速，6s的室性自主心律，频率为27次／分的窦性心动过缓，以及3～6s的窦性停搏，持续心脏按压．吸氧约2min后．患者意识恢复，心电图转为窦性心律，呈窦性心动过缓．LGL预激综合症，缺血性ST段压低，继续观察心电图变化，可见ST段压低有所缓解，遂送入病房，给予抗凝。抗血小板凝集，J3受体阻滞剂等治疗，7天后临床治愈出院。

简介：花生作为老百姓喜爱的传统食品之一,自古以来就有＂长生果＂的美誉。民谚道＂：常吃花生能养生＂,研究发现,其具有一定的药用价值和保健功能。1、降低胆固醇花生性味甘、平,可健脾和胃、润肺化痰、益气止血,用于脾虚消瘦、食少乏力、干咳少痰、产后乳汁不足等症。李教授介绍说,花生中的脂肪可使肝内胆固醇分解为胆汁酸,促进排泄,从而降低血中胆固醇含量,用以预防动脉粥样硬化。

简介：大多时候,期刊将注意力集中在已适用于治疗心脏病患者的治疗方法上。这篇文章却不一样。主编选了5个有关心血管健康的创新型科技,他预测我们会在接下来的几年里经常听到这些科技。诊断、治疗心脏病的创新设备和手术即将来临。1.谷歌眼镜众所周知的可佩戴计算技术——谷歌眼镜,是一款头戴式眼镜。这款复杂的微型计算机可以拍照,录制视频,无线传输数据。医生可以在进行医疗手术时,使用无手操作装置,录制和传输图片，不需要操作照相机，也不会弄脏无菌外科手术环境。

简介：例1患者男性，42岁。临床诊断：非对称性肥厚性心肌病。查心电图示：除V2导联S波增深达3．5mV以外，其余未见异常。查超声心动图示：心脏各房室腔径正常，房室间隔连续完整，室间隔心肌明显增厚，最厚处约1．8cm，增厚的心肌成毛玻璃样改变，动度减低。超声诊断：非对称性肥厚性心肌病。

简介：我国自古就有采集野生荠菜食用的习俗。如今又到了吃荠菜的季节了,荠菜味道鲜美,因其含有较高的味精成分——谷氨酸。您知道吗？荠菜也是一种中草药,有很高的药用价值及营养价值,被誉为＂菜中甘草＂,含有人体所需要的多种氨基酸。下面为您介绍荠菜都有哪些保健养生功效。
