Arrhythmias extracted from school-based cardiovascular screening accounts for a large number of asymptomatic diseases, and there are many cases where it is difficult to manage them. In this article, we outline the premature ventricular contractions (PVCs), long QT syndrome (LQT), and WPW syndrome extracted from school-based cardiovascular screening. PVCs are a form of benign arrhythmia, many of which do not require drug treatment or intervention. Although a differential diagnosis of catecholamine-induced polymorphic ventricular tachycardia (CPVT) is problematic, CPVT does not often exhibit PVCs at rest, and it is rarely is CPVT detected by PVCs extracted by screening. LQT is examined by treadmill tests and Holter recordings. The Fridericia correction is recommended for the correction formula. If LQT is suspected, exercise limitations, preventive medication, and genetic testing should be considered. Although WPW is a disease caused by an accessory pathway connecting the atrium and ventricle diagnosed by a Δ wave, the distinction between a fasciculoventricular pathway (FVP) and WPW syndrome becomes problematic. FVPs are a disease free from the risk of tachycardias and sudden death and it is important to understand the concept of the disease.
