| Recommendations for secondary prevention of sudden cardiac death in ischemic heart disease |
| ICD implantation (Class I, Level of Evidence B): |
|
❑ In patients with IHD and survivors of SCD due to VT, VF or hermodynamically unstable VT or incessant VT with irreversible cause, ICD should be implanted if survival is more than 1 year. |
| ICD implantation (Intermediate value statement, Level of Evidence B) : |
|
❑ In patients with higher risk of death due to ventricular arrhythmia and lower risk of non cardiac death due to other comorbidities, ICD implantation has intermediate value. |
| ICD implantation : (Class I, Level of Evidence B) |
|
❑ In patients with IHD and unexplained syncope with induction of sustained monomorphic VT in EPS, ICD implantation is recommended if life expectancy is more than 1 year |
