A smart-technology wearable wristband device may be able to automatically detect cardiac arrest, which could lead to faster medical assistance and increased survival odds when cardiac arrest occurs outside of a hospital, according to new research published in Circulation: Arrhythmia and Electrophysiology.
Cardiac arrest was accurately detected in 92% of cases: specifically, 100% of ventricular fibrillation and 90% of pulseless ventricular tachycardia.
In the per-patient analysis, considering only the first event per person, the accuracy for detecting the irregular rhythms was 92%.
In a future application, the algorithm from this study could be used to alert nearby lay rescuers, emergency services, or both, when someone having a cardiac arrest is detected.
