Is electrical storm a risk factor for mortality and morbidity, and what are its clinical predictors?
Electrical storm is a significant predictor of mortality and heart failure morbidity, and can be predicted by factors such as secondary prevention ICDs, monomorphic VT, lower ejection fraction, and class I anti-arrhythmic drug therapy.
Electrical storm is a strong mortality risk factor and it is associated with an increased combined risk of death, heart transplantation, and hospitalization for heart failure. Implantable cardioverter-defibrillator for secondary prevention, monomorphic ventricular tachycardia as triggering arrhythmia, lower ejection fraction, and class I anti-arrhythmic drugs therapy are all associated with ES and could be used to define specific populations with higher risk to develop ES.
