电击转复心律应采用多大的电功率,至今尚未统一。现将一例快速性室性心律失常用直流电小功率复律结果报告如下: 何××,男,59岁,病志号:5905。于1983年7月19日劳累后感气短,当晚20时出现剧烈胸痛,向左上肢放散,伴有心悸、头晕、恶心、多汗,于当晚21时15分急诊入院。患者曾于1979年以“急性前壁心肌梗塞”住某院。嗣后几年来心绞痛经常发作,服硝酸甘油后缓解。体检:体温36.0,脉搏200,呼吸20,血压90/80,意识清醒。两下肺少许细小湿罗音。心尖搏动在左第五肋间锁骨中线内0.5cm处,无震颤。心界左缘位于左侧第五肋间锁中线上。心率200, Electric shock should be used to recuperate how much power, has not yet unified. Now an example of rapid ventricular arrhythmia with DC low-power cardioversion results are as follows: He × ×, male, 59 years old, pathology number: 5905. On July 19, 1983 after the exhaustion, feeling short, severe night chest pain at 20 o’clock that night, to the left upper extremity exasperation, accompanied by palpitations, dizziness, nausea, sweating, 21:15 night emergency admission. The patient had a “acute anterior myocardial infarction” in 1979 to live in a hospital. Angina frequently over the next few years, after taking nitroglycerin relief. Physical examination: body temperature 36.0, pulse 200, breathing 20, blood pressure 90/80, conscious. A little wet two lungs rales. Apex beat in the fifth intercostal clavicle midline 0.5cm Department, no tremor. Left edge of the heart is located in the left fifth intercostal lock line. Heart rate 200,
