维拉帕米静脉注射历来被列为阵发性室上速的首选治疗,但有严重的电生理和血流动力学不良作用,对小儿可能致死。 32例阵发性室上速,压迫颈动脉窦后7例(22％)恢复窦性心律。另外25例随机静脉注射腺苷(14例)或维拉帕米(11例)。腺苷(2.5mg/ml)起始量40μg/kg,每2分钟增加1次,极量20mg;维拉帕米(5mg/ml)起始量70μg/kg,每5分钟增加1次,极量15mg。当腺苷剂量为40～120μg/kg时,86％ Verapamil intravenous traditionally has been listed as the preferred treatment of paroxysmal supraventricular tachycardia, but has serious adverse effects of electrophysiology and hemodynamics, may cause death in children. 32 cases of paroxysmal supraventricular tachycardia, compression of the carotid sinus after 7 cases (22%) to restore sinus rhythm. Another 25 patients were randomized to intravenous adenosine (n = 14) or verapamil (n = 11). The initial dose of adenosine (2.5mg / ml) was 40μg / kg, once every 2 minutes and the maximum amount was 20mg. The initial amount of verapamil (5mg / ml) was 70μg / kg, Amount 15mg. When adenosine dose is 40 ~ 120μg / kg, 86%
