Abstract
Dislodgement of a defibrillation lead from the right ventricle to the right atrium is a rare complication associated with implantable cardioverter-defibrillators. However, such dislodgement deserves attention out of proportion to its low incidence because of the possibility to cause fatal proarrhythmia. Various embodiments are directed to algorithms for detecting lead dislodgement, including a primary algorithm that operates during baseline rhythm and a secondary algorithm that operates during detection of ventricular tachycardia or ventricular fibrillation to identify lead dislodgement during atrial fibrillation.
