Does electrical storm increase mortality in patients with implantable cardioverter defibrillators?
Electrical storm is a frequent event in ICD recipients predicted by severe systolic dysfunction, chronic renal failure, and initial VT, but it does not independently increase mortality.
ES is frequent but does not increase mortality in ICD's recipients. Patients with severe systolic dysfunction, chronic renal failure and VT as initial arrhythmia are likely to experience ES. Diabetics are less affected by ES.
Brigadeau et al. (2006) studied this question.
