Case summary: We present a case of S-ICD implantation in a patient diagnosed with idiopathic ventricular fibrillation. In the first follow-up consultation the patient showed appropriate detection parameters in the three configurations. However, chest X-ray revealed lead displacement with a tip migration from the manubrium area of the sternum to the xiphoid process. Discussion: This case highlights the importance of performing at least one chest X-ray during the first weeks after S-ICD implantation, allowing the detection of a problem such as lead displacement, which can lead to undersensing of ventricular arrhythmias or S-ICD oversensing.5 p.application/pdfengcc-by-nc (c) Apolo, José et al., 2019http://creativecommons.org/licenses/by-nc/3.0/esRaigs XDesfibril·ladors cardioversors implantablesFibril·lació ventricularX-raysImplantable cardioverter-defibrillatorsVentricular fibrillationUndetected displacement of a subcutaneous implantable cardioverter-defibrillator leadinfo:eu-repo/semantics/article6983892020-06-01info:eu-repo/semantics/openAccess
