Abstract A 60‐year‐old male experienced an inappropriate shock from an implantable cardioverter‐defibrillator ( ICD ) because of oversensing of pectoral myopotentials. Battery depletion was also observed, and a generator change was performed. A single‐chamber ICD ( VENTAK PRIZM II 1860) was changed to a new ICD ( INCEPTA VR F161). The myopotentials were clearly eliminated by the difference in the band pass filter ( PRIZM ; 21‐171 Hz, INCEPTA ; 20‐85 Hz), but unfortunately, new noise was documented 4 years later. The utility of the bandpass filter for preventing oversensing of myopotentials was observed, but the limitation of its use for long‐term follow‐up was also indicated.
