A life-threatening arrhythmia induced by inappropriate activation of an implantable cardioverter defibrillator.
We describe an unusual case of near fatal inappropriate implantable cardioverter defibrillator therapies due to atrial oversensing by a newly implanted ventricular lead. Chest X-ray revealed dislodgement of the active fixation lead to the tricuspid annulus area explaining the atrial oversensing and intermittent ventricular therapies.
