Table 1 Indications for ICD implantation in HCM patients to prevent SCD
ICD Recommended (Class I) | ICD Reasonable (Class IIa) | ICD May be Useful (Class IIa) |
|---|---|---|
● Prior cardiac arrest | ● Family history of sudden death in first degree relative (age <50) | ● Non-sustained VT or abnormal BP response in presence of other SCD risk modifiers. |
● Sustained VT | ● LV wall thickness ≥ 30 mm | Note: Role of ICD is uncertain in non-sustained VT or abnormal BP response in absence of other SCD risk modifiers (Class IIb) |
● Recent unexplained syncope |
