Abstract
Skin biopsies obtained 24 hours after elective cardioversion of 30 patients showed variable epidermal necrosis and upper dermal perivascular inflammation, most noticeably in patients receiving high individual peak (> or = 300 J) and cumulative (> or = 350 J) shock energies. Thus, damped sine wave shocks cause skin injury--first degree burns--the severity of which is a function of peak and cumulative shock energy.
摘要
对30例患者进行择期心脏复律24小时后获取的皮肤活检显示，表皮坏死和真皮上部血管周围炎症情况各异，在接受高个体峰值（≥300焦耳）和累积（≥350焦耳）电击能量的患者中最为明显。因此，阻尼正弦波电击会导致皮肤损伤——一度烧伤——其严重程度是峰值和累积电击能量的函数。
