Does the newest generation of the AICD cause double counting of the QRS-T wave complex and asymptomatic discharges?
The newest generation of AICDs may cause asymptomatic discharges due to T wave oversensing, highlighting a dilemma between detecting fine ventricular fibrillation and avoiding diastolic event sensing.
Singer et al. (1988) conducted an observational in Patients requiring an Automatic Implantable Cardioverter Defibrillator (n=76). Newest generation Automatic Implantable Cardioverter Defibrillator was evaluated on Double counting of the QRS-T wave complex resulting in asymptomatic discharges. The newest generation of the Automatic Implantable Cardioverter Defibrillator caused double counting of the QRS-T wave complex resulting in asymptomatic discharges in 7.9% (6 of 76) of patients.
