In Alejandro Fernandez v. Techno Cable Wiring and MSA Group the Claimant was injured at his place of employment and received pain management treatment which included injections in his lumbar area. When Claimant went for his third injection he suffered from a cardiac arrhythmia and was transported to the hospital. The claimant then began to receive hospital bills for these emergency services. The JCC stated that Claimant had the burden of proving the causal relationship between the scheduled sympathetic block and atrial fibrillation. The JCC found that there was no direct medical evidence establishing a relationship between the two events. The JCC DENIED claim for payment of bills. The DCA AFFIRMED the decision per curiam.
