'''心动过速'''（tachycardia），指每分钟心率超过100次。心动过速分生理性、病理性两种。跑步、饮酒、重体力[[劳动]]及情绪激动时心律加快为生理性心动过速；若高热、贫血、甲亢、出血、疼痛、缺氧、心衰和心肌病等疾病引起心动过速，称病理性心动过速。如果心跳过快以至于不能维持有效的血液循环时，可以出现心悸、胸痛、头昏、眩晕、昏迷或半昏迷等症状。发生心动过速时，心律可能规则或不规则。紧急时嘱患者[[咳嗽]]、深呼吸、刺激咽部、压迫眼球等方法缓解某些心动过速；药物可暂时的“终止”发作；射频消融术可根治某些心动过速。<ref>[https://www.chunyuyisheng.com/pc/topic/256024/ 心动过速有什么危害],春雨医生 , 2018年8月22日</ref>
