ESC Guidelines: ICD therapy for HFrEF (English Version)

Is ICD really beneficial for HF patients?
When to think of ICD for a HF patient?
Is primary prevention ICD of doubtful benefit for HF patients?
What is the role of S-ICD & WCD?

Let's elaborate this discussion based on the 2021 ESC Guidelines of HF.
