患者女性,23岁。农民。因与家人争吵服杀虫脒100ml约3小时于1987年8月11日6时急诊来院,平素健康。体检:体温37℃,脉博58次/分,呼吸20次/分,血压12/8kPa。深昏迷,唇绀,两侧瞳孔0.4cm,等园等大;光反射迟钝。颈软,心率58次/分,律齐,心尖区Ⅱ级吹风样收缩期杂音,心界不扩大。两肺呼吸音粗糙。腹软。肢端末梢发绀。神经系统未引出病理反射。入院后立即给予输氧、洗胃、美蓝解毒及呼吸兴奋剂等处理,约10小时后,神转清,发绀减轻,但于次日上午10时出现心悸、胸闷等不适。体检:唇绀,心率60～62次/分,律不齐,心音低钝,血压12/8kPa。心电图:心悸、胸闷时各QRS波振幅大小形态不全相同,心率200次/分,每隔3～5个心搏可见QRS主波方向突然转至相反方向形成围绕基线的上下扭转现象,发作时间2～5秒,发作间歇期呈窦性心律,心率60次/分,各导联可见明显u波,Ⅲ、aVF、V_1、V_3T波和u波呈双峰状,Q-T间期0.50～0.52秒。实验室检查:血钾3mmol/L,血钙2mmol/L,尿检蛋白+、红细胞+++,白细胞少许。根据临床症状和心电图报告,考虑扭转性室性心动过速。即刻给予异丙基肾上腺素lmg加入5％葡萄糖盐水250ml静滴并以l～2μg/分维持滴速,补充钾盐及能量合剂等处理。心电图动态观察:发作次数减少,发作间歇期延长。入院后第3天晨患者自觉胸 Patient female, 23 years old. Peasants. Quarrel with their families serving chlordimeform 100ml about 3 hours at 6 o’clock on the August 11, 1987 emergency room to the hospital, usually healthy. Physical examination: body temperature 37 ℃, pulse Bo 58 / min, breathing 20 beats / min, blood pressure 12 / 8kPa. Deep coma, cyanosis, both sides of the pupil 0.4cm, garden and other large; slow light reflex. Neck soft, heart rate 58 beats / min, law Qi, apnea Ⅱ grade hair-like systolic murmurs, the heart does not expand. Breathe sound rough between the two lungs. Abdomen soft. Extremities cyanosis. The nervous system does not elicit pathological reflexes. Immediately after admission, oxygen, gastric lavage, methylene blue detoxification and respiratory stimulants were given. About 10 hours later, God turned clear and cyanosis was relieved. However, heart palpitations, chest tightness, and other discomfort were found at 10 am the next day. Physical examination: cyanosis, heart rate 60 ~ 62 beats / min, irregularities, low heart sound, blood pressure 12 / 8kPa. ECG: palpitations, size and shape of each QRS wave amplitude chest tightness same failure, heart rate 200 beats / min, three to five heartbeats visible QRS main wave direction suddenly go down in the opposite direction is formed around the base torsion every phenomenon, time of onset 2 ~ 5 seconds, intermittent seizure was sinus rhythm, heart rate 60 beats / min, each lead showed obvious u wave, Ⅲ, aVF, V_1, V_3T wave and u wave was bimodal, QT interval 0.50 ~ 0.52 seconds. Laboratory tests: potassium 3mmol / L, calcium 2mmol / L, urine protein +, red blood cells +++, a little white blood cells. According to the clinical symptoms and ECG reports, consider the reversal of ventricular tachycardia. Immediately given isoproterenol lmg add 5% dextrose 250ml intravenous drip and l ~ 2μg / min to maintain drip rate, potassium salt and energy mixture and other treatment. ECG dynamic observation: reduce the number of seizures, seizures intermittent extended. On the third day after admission, patients conscious chest
