Wearable defibrillators (WCD) use skin electrodes (SE) for rhythm monitoring and response buttons (RB) to allow patients to divert unneeded or inappropriate shocks (IAS). Recently we reported deaths caused by arrhythmogenic WCD IAS. However, outcomes of IAS in the general WCD population have not been described. Assess the causes and consequences of inappropriate shocks (IAS) received by patients while wearing the LifeVest 4000 WCD (ZOLL Medical), and evaluate RB usage and efficacy. The Food and Drug Administration's Manufacturers and User Facility Device Experience (MAUDE) was queried for descriptions of events and stored ECG findings of WCD patients who received inappropriate shocks (IAS) outside the hospital and survived. From November 2021 to November 2022, 1,312 patients received IAS (avg 1.55±1.84SD, range: 1-29). IAS were caused by atrial fibrillation (n=391;29.8%), supraventricular tachycardia (n=218;16.6%), non-sustained ventricular tachycardia (VT) or non-sustained ventricular fibrillation (VF) (n=41;3.1%), oversensing of ECG signals (n=236;18.0%), and motion/noise artifacts (n=426;32.5%). IAS in 13 patients (0.1%) induced VT or VF that were subsequently and appropriately shocked and terminated. IAS resulted in 8 falls and 3 fractures, and at least 208 patients (15.9%) discontinued the WCD after receiving IAS. Of 74 patients who received IAS while riding a vehicle, 52 (70.2%) occurred on a motorcycle and 8 (10.8%) on a lawnmower. Only 560 (42.7%) patients attempted to divert impending IAS using the response buttons (RB); RB use by 144 (25.7%) patients failed to abort the shock, and the remaining patients pressed the RB only after shock delivery. The results of this study suggest: 1) Most IAS are due to inaccurate rhythm discrimination and electrogram oversensing; a third are caused by SE motion, especially motor vibrations. 2) IAS may be arrhythmogenic and they promote noncompliance. 3) Improved methods for preventing and aborting IAS are needed.
