Event or Problem Description
It was reported that the cardiac resynchronization therapy defibrillator (crt-d) detected an episode of slow ventricular tachycardia (vt) as supra ventricular tachycardia (svt) and inappropriately withheld therapy.It was suspected that the inappropriate detection may have been due to the crt-d feature that functions as a svt discriminator and is used to distinguish between rapid and gradual onset of fast ventricular rhythms.It was further reported that the right atrial (ra) lead exhibited high thresholds.The crt-d and the ra lead remain in use.No further patient complications have been reported as a result of this event.
