闪电能让你的心脏重新跳动吗?

吉姆·钱德勒医生，根西岛伊丽莎白公主医院心脏麻醉师顾问:

首先，简短的回答是肯定的，被闪电击中两次可能会先让你的心脏停止跳动，然后又让你的心脏重新跳动。但答案要比这复杂一点。心脏细胞之间保持电压降，控制离子的流入和流出。这些离子使心脏跳动。如果心脏被闪电击中，电压会立即下降，心脏会收缩。不幸的是，如果闪电在心脏松弛的错误部位击中心脏，细胞就不会一起收缩，而是混乱地收缩。心脏将进入一种叫做纤颤的节律。这使它无法泵出。因此，脉搏会停止跳动，心脏就会停止跳动。如果在心脏跳动的同一时刻发生第二次闪电或电击，心脏细胞可能会以更有序的方式收缩在一起。 However, there is a problem. The heart could also be struck by lightning and instead of going into this fibrillating chaotic rhythm it could go into no rhythm at all. It could quite simply not beat again. That's called asystole. It doesn't end there unfortunately, our poor unfortunate victim also suffers elsewhere. It's likely that the chest would become relatively stiff and the chest muscles would go into spasm. These muscles take a lot longer to recover than heart muscles so it would be very unlikely that your victim would be able to breathe again. For that reason, although the heart may well restart the victim may well die.
