Appropriate use of wearable defibrillators with multiparametric evaluation to avoid unnecessary defibrillator implantation.

The use of WCD for patients at high risk of arrhythmias allowed to optimise therapy and limit the indications for ICD. Inappropriate implantation of ICD was avoided in 69% of patients who received WCD. The device showed a good safety profile, low incidence of device interventions and adequate patients' adherence to WCD use.
