Which body part is most susceptible to electrical shock?

The heart is the body part most susceptible to electrical shock due to its critical role in maintaining the body's circulatory system. Electric current can interfere with the heart's electrical signals, leading to arrhythmias, which are irregular heartbeats. In severe cases, exposure to electrical shock can result in cardiac arrest, where the heart stops pumping blood effectively, posing an immediate life-threatening situation.

While the brain, hands, and feet are also vulnerable to the effects of electrical shock, particularly in terms of nerve damage or burns, the heart's specific susceptibility to disruptions caused by electrical current is what makes it the most critical focus when considering the dangers associated with electrical exposure. The heart's reliance on electrical impulses for its function underscores the importance of safety measures when working with or near electrical systems.
