["Crows' feet wrinkles" in high voltage electric accident--a sign of survival?].
A "crowsfoot-like" pattern is considered as being a sign of vitality in fatalities due to the effects of smoke, fire or high voltage (active or reflex contraction of mimic muscles). Introducing the autopsy results of a high voltage accident (66,600 V) it is discussed, whether this phenomenon and the underlying contraction of the facial muscles could also be caused by electrical current in the agony or supravital period. It seems possible that this mechanism of direct muscle contraction anticipates a nerval indirect stimulation of muscle fibres by innervating motoneurones--active or on the basis of a polysynaptic extraneous reflex. If the electrophysiological course discussed should be right, a "crowsfoot-like" pattern in equivalent cases could be interpreted as a vital sign only with great reserve.
