초록
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.
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.
