Guglielmo’s employment history is straightforward. He spent 23 years as a police officer before joining the DOC. In March 2021, he resigned from his corrections job, citing health concerns and exhaustion from long hours. At the time he left, his weekly wage was $673.20. Four months later, on July 16, 2021, Guglielmo experienced heart palpitations and was diagnosed with atrial fibrillation after a trip to the emergency room. He reported the condition to the DOC and filed a workers’ compensation claim under Florida’s “heart-lung statute,” which presumes certain heart conditions in first responders and corrections officers are work-related, provided the claim is filed within 180 days of leaving employment. Guglielmo filed his claim about 119 days after resigning.
