To determine patient compliance and effectiveness of antiarrhythmic treatment by the wearable cardioverter-defibrillator (WCD). Effectiveness of the WCD for prevention of sudden death is dependent on event type, patient compliance and appropriate management of ventricular tachycardia/fibrillation (VT/VF). Compliance and events were recorded in a nation-wide registry of post-market release WCDs. Survival, using the Social Security Death Index, was compared with survival in implantable cardioverter-defibrillator (ICD) patients. Of 3569 patients wearing the WCD (age 59.3±14.7, duration 52.6±69.9 days), daily use was 19.9±4.7 hours (>90% of the day) in 52% of patients. More days of use correlated with higher daily use (p<0.001). Eighty sustained VT/VF events occurred in 59 patients (1.7%). First shock success was 76/76 (100%) for unconscious VT/VF and 79/80 (99%) for all VT/VF. Eight patients died after successful conversion of unconscious VT/VF (survival 89.5% of VT/VF events). Asystole occurred in 23 (17 died), pulseless electrical activity in 2 and respiratory arrest in 1 (3 died), representing 24.5% of sudden cardiac arrests. During WCD use, 3541/3569 patients (99.2%) survived overall. Survival occurred in 72/80 (90%) VT/VF events and 78/106 (73.6%) for all events. Long-term mortality was not significantly different from first ICD implant patients but highest among patients with traditional ICD indications. Compliance was satisfactory with 90% wear time in >50% of patients and low sudden death mortality during usage. Survival was comparable to that of implantable ICD patients. However, asystole was an important cause of mortality in sudden cardiac arrest events.
