患者,男,9岁,因先心病室间隔缺损入院后行室间隔修补术,当晚22时病人心室率突然减慢29次/分BP70/50mmHg,神志不清,四肢末梢凉,用阿托品,异丙肾,及升压药效果不著,心室率仍为29～30次/分,此时血压已降至50/30mmHg。即自鼻孔插入电极导管,深度35cm,尾端连接苏州电子仪器厂 XD—Ⅱ型程控刺激仪,以100次/分,电压30V 试行起搏成功,心电图示波出现起搏心电图,2分钟后血压恢复至
Patients, male, 9 years old, were admitted to the hospital due to congenital heart disease ventricular septal defect after ventricular septal repair, 22:00 the night the patient’s ventricular rate suddenly slowed down 29 times / min BP70 / 50mmHg, unconscious limbs cold, with atropine, C kidney, and vasopressors ineffective, ventricular rate was still 29 to 30 beats / min, then the blood pressure has dropped to 50 / 30mmHg. That is inserted from the nostril lead electrode, the depth of 35cm, the tail connected to the Suzhou Electronic Instrument Factory XD-Ⅱ-type program-controlled stimulator to 100 times / min, voltage 30V pilot pacing success, electrocardiogram oscilloscope pacing ECG, blood pressure after 2 minutes Recover to
