Key result
The GuardianR ATP 4210 ICD demonstrated undersensing of ventricular fibrillation and caused inappropriate asystole and prolonged bradycardias due to shortcomings in its reconfirmation algorithm.

Does fixed gain sensing and arrhythmia reconfirmation in the GuardianR ATP 4210 ICD pose safety hazards in patients?
Fixed gain sensing and specific tachyarrhythmia reconfirmation algorithms in ICDs can lead to hazardous undersensing of VF and inappropriate asystole.
Singer et al. (1993) conducted a case report in Ventricular tachycardia and ventricular fibrillation requiring ICD (n=1). GuardianR ATP 4210 ICD was evaluated on Undersensing of VF and inappropriate episodes of asystole and prolonged bradycardias. The GuardianR ATP 4210 ICD demonstrated undersensing of ventricular fibrillation and caused inappropriate asystole and prolonged bradycardias due to shortcomings in its reconfirmation algorithm.
