title: Rate adaptive dual chamber pacing: inappropriate rate response due to pseudomalfunction of the QT biosensor.
abstract: Inappropriate tachycardias may be observed in patients with DDDR pacemakers equipped with an activity sensor and a QT sensor due erroneous T wave sensing, provoked by drug treatment that prolongs cardiac repolarization.
