Electrical Injury

The Unwanted Power Surge Through Your House

Imagine your body is a house with electrical wiring. Normally, the house's wiring (nerves and blood vessels) carries carefully controlled, low-voltage signals—like a dimmer switch adjusting lights smoothly. Your skin is like the rubber insulation around each wire; it stops stray current from entering. But when lightning strikes the house (high-voltage electrical contact), or when you're wet and touch a live wire (water removes insulation), the current bypasses the rubber coating and floods into the wires themselves. This massive, uncontrolled current heats up the wires from the inside—like turning a toaster coil to maximum—cooking the insulation and the copper beneath (this is the deep tissue burn). Meanwhile, your heart is like the house's main circuit breaker, which is supposed to trip safely when it detects a surge; instead, external current electrocutes the breaker itself, making it either jam in the 'on' position (ventricular fibrillation—chaotic firing) or flip completely off (asystole—total stop). Your muscles are like appliances that normally respond to a dimmer switch; instead, they receive a full-voltage blast and contract so hard they break themselves (like an overloaded motor seizing up). Finally, when muscle gets cooked badly enough, it leaks its contents (myoglobin) into the pipes (blood vessels), and that protein clogs the water filter (kidneys) downstream, backing up the whole system.
