Abstract
- Inappropriate shocks from an implantable cardioverter defibrillator (ICD) can cause potentially dangerous ventricular arrhythmias and impaired quality of life. We describe a case in which a dislodged lead caused inappropriate ICD shocks through simultaneous sensing of atrial and ventricular signals. Interestingly, repeated short-long R-R sequences were recorded, but ICD interrogation parameters were usually unchanged.
