胸外电击除颤使用电能大小,尚无法提出固定数字;常倾向于认为越大效果越好。但在动物实验上,曾显示高电能似不如低电能更为有效。Weaver等,于1982年发表了249例在医院外发生的心跳骤停病例中,随机使用175瓦·秒或320瓦·秒的除颤效果。在其它复苏措施使用的同时,两组胸外电击除颤第一次的效果相同;皆有61％患者成 Thoracic electric shock defibrillation using the size of the energy, still can not propose a fixed number; often tend to think that the greater the better. However, in animal experiments, it has been shown that high electrical energy may not be as effective as low electrical energy. Weaver et al., Published in 1982, 249 cases of cardiac arrest occurred outside the hospital, randomized to 175 watts-seconds or 320 watts-seconds defibrillation. At the same time as other recovery measures were used, the first two episodes of thoracic shock were the same; both 61%
