Recordings of alerts from the wearable cardioverter defibrillator during the surveillance period. Patient (A) reported worsening of dyspnea, with the electrocardiographic confirmation of atrial fibrillation. In the lower panel are depicted the daily heart rate trends from the same patient, with a sudden increase of the heart rate suggestive for an arrhythmic event. (SS: side-side electrodes, FB: front-back electrodes) Recording from the wearable cardioverter defibrillator of an episode of non-sustained ventricular tachycardia in patient (B) with non-ischemic cardiomyopathy.
