Theoretical representation of the differences in all‐cause mortality and proportional SCD risk as a function of left ventricular ejection fraction and the impact on potential defibrillator benefit. Although patient A has a higher absolute risk of SCD, the benefit to defibrillator therapy may be attenuated as a function of lower proportional sudden death risk. ICD indicates implantable cardioverter‐defibrillator; SCD, sudden cardiac death.
