异搏停是一种钙拮抗剂,抑制房室结动作电位的0相和4相,从而消除折返激动。我们用静注异搏停治疗阵发性室上性心动过速10例。这10例中,男4女6,17~60岁,冠心病2例,心肌病2例,心肌炎1例,功能性5例。发作时均有心电图记录,心率160~200次/分。血压皆在90/60毫米汞柱以上。3例曾用西地兰或美速克新未能终止,余多用迷走神经刺激法无效。取异搏停5mg于20毫升5~50％葡萄糖溶液内缓慢静脉注射,并用听诊或心电图监测,一旦心率突然减慢或复窦即停止注射。如注完5毫克尚未见效,等15分钟再重
Verapamil is a calcium antagonist, inhibit the action potential of the atrioventricular node 0 and 4, thereby eliminating the reentry excitement. We used intravenous verapamil to treat paroxysmal supraventricular tachycardia in 10 cases. Among these 10 cases, 4 were female, 6-17 years old, 60 years old, 2 were coronary heart disease, 2 were cardiomyopathy, 1 was myocarditis, and 5 were functional. Have episodes of ECG records, heart rate 160 ~ 200 beats / min. Blood pressure is above 90/60 mmHg. 3 cases had used cedilanid or mesotr failed to terminate, more than vagus nerve stimulation ineffective. Take 5 mg of verapamil in 20 ml of 5 ~ 50% glucose solution slowly intravenous injection, and with auscultation or ECG monitoring, once the heart rate suddenly slowed down or complex sinus that injection. Such as Note End 5 mg has not worked, wait 15 minutes and then re-
