[A life-saving shock from a subcutaneous ICD during skydiving].

We report the case of a 38-year-old man who was implanted a subcutaneous implantable cardioverter-defibrillator (S-ICD) and then performed a skydive from a height of 3000 m. During the jump, he lost consciousness due to ventricular fibrillation (VF). The S‑ICD detected the VF properly and successfully shocked the arrhythmia. Our illustrative case emphasizes the S‑ICD as an appropriate therapy in patient with life-threatening arrhythmias even under extreme conditions.
