Dr Luca Santini (G. B. GRASSI Hospital, Italy) focused on the role of the wearable cardioverter defibrillator (WCD) during the high-risk phase in HF-patients. He concludes that the high-risk phase of HF poses a considerable threat of SCD, necessitating temporary protection strategies. A WCD can offer a valuable solution by providing continuous monitoring and the ability to deliver life-saving shocks when dangerous arrhythmias are detected.
