Arrhythmia Detection Algorithm
The Hospital Wearable Defibrillator (HWD) is able to identify life-threatening VT/VF using an arrhythmia detection algorithm. It was developed by ZOLL® and is also used on the LifeVest® wearable defibrillator. The detection algorithm analyzes both heart rate and morphology, making it highly sensitive and specific to treatment of ventricular arrhythmias.
Sensitivity and Specificity
The HWD has high sensitivity to VT and VF; it correctly identifies VT as VT and VF as VF. The HWD also has extremely high specificity for VT and VF. This means that rhythms that are excluded from treatment are not VT or VF.
Detection Algorithm
The detection algorithm looks primarily at two criteria, heart rate and QRS morphology, to define a treatable arrhythmia.
The Hospital Wearable Defibrillator is currently available in Singapore, Malaysia, and Thailand. Please contact your local ZOLL representative for more information.
