Cardiac rhythm recorded by implanted loop recorder during lightning strike

Lightning strikes cause severe injuries and fatalities. Injuries vary from self-limiting skin manifestations to cardiac arrest and death. Because the event is sudden and unpredictable, assessment of the direct effects of the lightning on the human heart is usually impossible. In this case, a 16-year old boy who had an implanted loop recorder subcutaneous cardiac monitor was hit by lightning during a picnic and survived. A cardiac rhythm strip was recorded live during the strike.
