阵发性室上性心搏过速

阵发性室上性心搏过速(英语:Paroxysmal supraventricular tachycardia,簡稱 PSVT室上性心搏过速中的一种[6]。一般患者不会出现症状[1],若有则可能是心悸、头重脚轻、盗汗、呼吸困难胸痛[2],症状出现得快,也消失得快[3]

病因尚属未知[3],风险因子有酒精、咖啡因尼古丁心理压力及遗传得来的沃夫巴金森怀特症候群[3]。此疾病的机制和副传导路径英语accessory pathway有关,会造成进入错误回路(英语:re-entry)的心律不整[3]。诊断会借由心电图(英语:ECG)来进行,若有窄QRS波群英语narrow QRS complexes且心律较快,在每分钟150至240下之间,即可确诊为阵发性室上性心搏过速[3]

常见的初步治疗为采用迷走神经刺激术英语Vagal maneuver,例如持续闭气用力英语Valsalva maneuver(又称伐氏操作),如果不见效且患者血压正常,可能会采用腺苷;如果腺苷没有帮助,可能会采用钙离子通道阻滞剂β受体阻滞剂;或者会改采心率调整来治疗[4]。预防之后发作的方法是心导管烧灼术英语Catheter ablation[3]

在每千人中约有2.3人患有阵发性室上性心搏过速[5],通常发病于12~45岁[3][5],女性患者较男性患者为多[3]心脏健全者的治疗成效往往也很好[3]。在厘清心脏病症时,可能会借由心脏超声波来做判断[1]
