室上性心动过速是一种較常見的心律紊乱,据Katz~1氏和张美祥等統計,約占所有心律紊乱之7.3—7.6％。虽然大多数預后尚好,如发作时間持續較久,則可使动靜脉血氧飽和度下降,血压降低,冠状动脉血流量减少,因而可以引起冠状动脉供血不足,心力袞竭,休克,甚至死亡。室上性心动过速的治疗方法虽多,但在危重情况下,可以立即糾正心律者却很少。本院在最近三年内,試用血管加压药(去甲腎上腺素及甲氧胺)治疗室上性心动过速,能够立即終止发作,且无严重併发症,值得应用。
Supraventricular tachycardia is a more common heart rhythm disorder, according to Katz ~ 1 and Zhang Meixiang statistics, accounting for about 7.3-7.6% of all cardiac rhythm disorders. Although most of the prognosis is good, such as attack longer duration, can make arteriovenous oxygen saturation decreased blood pressure, coronary blood flow decreased, which can cause coronary insufficiency, heart failure, shock, or even death. Supraventricular tachycardia treatment of many, but in critical cases, you can immediately correct heart rhythm but very few. Our hospital in the last three years, the trial of vasopressor (norepinephrine and methoxyamine) treatment of supraventricular tachycardia, can immediately stop the attack, and no serious complications, it is worth applying.
