Event or Problem Description
It was reported that the right atrial (ra) lead exhibited undersensing during atrial tachycardia/atrial fibrillation (at/af) events resulting in unnecessary pacing at times.Intermittent undersensing also resulted in misclassification of a detected ventricular tachycardia (vt) episode that was treated with anti-tachycardia pacing (atp) therapy.The ra lead remains in use. it was also reported that the patient received atp and high voltage therapy from the cardiac resynchronization therapy defibrillator (crt-d) for possible atrial tachycardia/atrial fibrillation (at/af) with fast ventricular response that the device detected as vt.There were also monitored episodes of possible at/af with fast ventricular response that were detected as non-sustained ventricular tachycardia.Functional undersensing in blanking/refractory on the ventricular channel also resulted in overpacing.The crt-d remains in use. no further patient complications have been reported as a result of this event.
