Does programming sudden onset and stability detection criteria with a sustained rate duration safety net improve appropriate device management in patients with implantable defibrillators?
Programming sudden onset and stability detection criteria with a sustained rate duration safety net allows for appropriate device management of supraventricular and slow ventricular tachycardias.
INTRODUCTION: Enhanced detection criteria in third-generation implantable defibrillators have been implemented to avoid inappropriate therapy of fast supraventricular arrhythmias. We prospectively analyzed the use of these criteria in patients with an implantable defibrillator with electrogram storing capability. METHODS AND RESULTS: In 82 consecutive patients with a Guidant-CPI implantable defibrillator, sudden onset > 9% and stability 9% and stability < 40 msec was the algorithm with the best specificity and sensitivity. CONCLUSION: Programming sudden onset and stability detection criteria with a sustained rate duration safety net for triggering tachycardia therapy results in appropriate device management in most patients with supraventricular and slow (< 210 beats/min) ventricular tachycardias.
