Which type of burn can affect the cardiac conduction system, resulting in arrhythmias or sudden death?

Electrical burns are particularly dangerous because they can have serious implications beyond the visible injuries on the skin. When an electric current passes through the body, it can disrupt normal cardiac function by affecting the heart's conduction system. This disruption can lead to arrhythmias, which are irregular heartbeats, and in severe cases, can result in cardiac arrest and sudden death.

The mechanism behind this is that electricity can create a pathway through the body, causing direct damage to the heart tissue or altering its electrical signals. Unlike other types of burns, the internal injuries from electrical burns may not always be immediately apparent, as the focus often lies on external injury. However, the potential for life-threatening heart complications makes electrical burns unique and a priority for assessment and treatment.

Other types of burns, such as chemical and thermal burns, primarily harm the skin and underlying tissues but do not typically have the same direct effects on the cardiac conduction system. Radiation burns can lead to cell damage and long-term complications but do not specifically interfere with cardiac rhythm in the same immediate and acute manner as electrical burns do. Therefore, when assessing burns with respect to cardiac risk, electrical burns are distinctly harmful due to their potential to disrupt heart function directly.
