During a period of 20 years, 8 patients with atrial fibrillation, without other cardiac abnormalities, resistant to electroconversion, but successfully defibrillated with quinidine, were examined. All were males, aged 40 to 50 years, working with electric current and exposed for many years to frequent electric shocks. The authors consider that chronic exposure to electric current induces a special form of atrial fibrillation, resistant to electric conversion. The inefficiency of the electroshock therapy in such cases might be explained by the increase of transthoracic impedance consecutive to repeated electrocutions.
在20年期间，对8例心房颤动患者进行了检查，这些患者无其他心脏异常，对电复律有抵抗，但用奎尼丁成功除颤。所有患者均为男性，年龄在40至50岁之间，从事与电流相关工作且多年来频繁遭受电击。作者认为，长期暴露于电流会诱发一种特殊形式的心房颤动，对电复律有抵抗。在这种情况下，电击疗法无效可能是由于反复电击后胸壁阻抗增加所致。
