What happens if electrical current between 100 and 200 milliamperes is absorbed by the body?

When electrical current between 100 and 200 milliamperes passes through the body, it can have extremely dangerous effects, particularly concerning the heart's function. This range of current can indeed disrupt normal cardiac function, potentially leading to immediate cardiac arrest or heart failure. The heart's electrical system is highly sensitive, and such a current can cause ventricular fibrillation, where the heart beats erratically and cannot pump blood effectively. This can lead to instant death if not treated promptly with defibrillation or other medical intervention.

The impact on the body at this current level means that immediate attention and intervention are critical, emphasizing the dangers of electrical shock injuries in this range. While severe muscle contractions and other effects can occur at lower current levels, the specific lethal potential of 100 to 200 milliamperes is most closely associated with the risk of instant heart failure.
