ABSTRACT
Premature ventricular contraction(PVC)is one of the most common types of arrhythmias in children.PVC in children usually disappears with age gradually and doesn't affect cardiac function and has a fa-vorable prognosis.Some PVC patients may have malignant arrhythmias or cardiomyopathy,which cause the de-creased ventricular systolic function,and even cardiac arrest,leading to poor prognosis.PVC can be classified to functional and structural type,and can also be classified according to the origin site.Until now,there are still no well-accepted standards to assess the prognosis and treatments of PVC in children.The PVC therapy in children mainly depends on the PVC frequency,type and the presence of congenital heart disease.Currently,propafenone, β-blocker and amiodarone are the nost commonly used drugs in PVC.Radiofrequency ablation(RFA)is another way of treating refractory cases. In this paper,we reviewed the prognosis of different types and therapies of PVC,and hope it could guide the clinical treatments of PVC in children.
