Quick Answer
There is limited evidence to suggest that lightning strikes directly increase the risk of heart attack, but the intense electrical surge can cause cardiac arrest, which can lead to the appearance of a heart attack.
Lightning Strike and Cardiac Arrest
Lightning strikes can cause cardiac arrest due to the intense electrical current passing through the body, disrupting the heart’s normal rhythm. This can happen even if the person is not showing any signs of cardiac issues beforehand. According to the National Weather Service, the electrical current from a lightning strike can reach temperatures of up to 50,000 degrees Celsius, five times hotter than the surface of the sun.
First Aid for Lightning Strike Victims
When treating a victim of a lightning strike, it’s essential to prioritize CPR and cardiac arrest protocol. The American Red Cross recommends starting CPR with 30 chest compressions followed by two breaths, repeating this cycle until medical help arrives. It’s also crucial to assess the victim’s airway, breathing, and circulation (ABCs) to identify any other potential injuries, such as burns or neurological damage.
Storm Safety and Prevention
Preventing lightning strikes is always the best course of action. If there’s a thunderstorm in the area, seek shelter immediately in a sturdy building or a hard-topped vehicle with the windows closed. Avoid open areas, such as beaches, fields, or golf courses, and stay away from conductive objects like metal fences or golf clubs. If you’re caught outside and can’t get to shelter, crouch low with your feet together and your head down, minimizing your chances of being struck by lightning.
