What are the clinical characteristics and prognostic factors associated with pediatric ventricular tachycardia?
Odds Ratio: 11.7 (95% CI 1.7–78.4)
Absolute Event Rate: 40% vs 5.4%
p-value: p=0.012
The prognosis of pediatric ventricular tachycardia depends heavily on its etiology, with catecholaminergic polymorphic VT, cardiomyopathy-associated VT, polymorphic VT, and sustained VT carrying a significantly higher risk of death or cardiac arrest.
Song et al. (2010) conducted an observational in Pediatric Ventricular Tachycardia (n=81). Catecholaminergic polymorphic ventricular tachycardia (CPVT) vs. Idiopathic ventricular tachycardia (IVT) was evaluated on Sudden death or cardiac arrest (OR 11.7, 95% CI 1.7-78.4, p=0.012). Catecholaminergic polymorphic ventricular tachycardia significantly increased the risk of sudden death or cardiac arrest compared to idiopathic ventricular tachycardia (OR 11.7).
