Pediatricians often encounter some electrocardiographic abnormalities in infants and children. However, treatment or referral to pediatric cardiologist is not indicated for all arrhythmias. Many of them are benign in nature. Benign arrhythmias can be defined as the arrhythmias that no serious problem currently exists and no treatment is needed. The prognosis of benign arrhythmias is so good that the condition will never be associated with future health problem. However, some of them are benign now, but have potential for variable degrees of change to a nonbenign condition and some form of follow-up is required. For the appropriate management of electrocardiographic abnormalities, not infrequently seen in infants and children, correct diagnosis of abnormal electrocardiogram and understanding of characteristics of arrhythmias are required.

Concerning expansion of physical facilities by 2010, this study was attempted to diagnose whether or not the government's will of policy is leading to systematic expansion of them at the current point of time and analyze effectiveness of the performance. Analysis was conducted with primary data of empirical materials obtained through inquiry into the physical facilities of advanced countries, policy materials for public physical facilities being promoted in Gyeonggi- do, and materials of the reported and registered physical facilities as issued by the Ministry of Culture and Tourism and secondary data of statistical materials for public physical facilities in order to propose the lines of policy for development of physical facilities environment in Gyeonggi-do as a part to indicate the appropriateness of physical facilities supply policy. By this methodology, three suggestions are made as follows: First is to secure space efficiency of public stadiums in Gyeonggi -do. The relevant line of policy is primarily to examine plan for optimal utilization of various public physical facilities in provinces. With this, part of the seats whose space use rate is just 3% should be remodeled as space for residents' rest and sports activity. Second is to develop public sports park suited to the local characteristics. The relevant line of policy should be divided into 3 types - urban type, urban- rural complex community type, rural type - and the park should also be divided into 3 types according to degree of population congestion - centralization type, decentralization type, fundamental type - in order to increase the availability of park facilities. Third is to set up specialized leisure sports facilities by region. As the relevant line of policy, selection of subject area and establishment of detailed guidelines are required. Private investment should also be induced through substantial institutional support and incentives from the nation and local government.

Left ventricular (LV) dysfunction and dilated cardiomyopathy (DCM) are rarely attributable to sustained or incessant tachyarrhythmias in infants and children with Wolff-Parkinson-White (WPW) syndrome. However, several recent reports suggested that significant LV dys-function may develop in WPW syndrome in the absence of tachyarrhythmias. It is assumed that an asynchronous ventricular activation over the accessory pathway, especially right-sided, induces septal wall motion abnormalities, ventricular remodeling and ventricular dys-function. The prognosis of DCM associated with asymptomatic WPW is excellent. Loss of ventricular pre-excitation results in mechanical resynchronization and reverse remodeling where LV function recovers completely. The reversible nature of LV dysfunction after loss of ventricular pre-excitation supports the causal relationship between LV dysfunction and ventricular pre-excitation. This review summarizes recent clinical and electrophysiological evidence for development of LV dysfunction or DCM in asymptomatic WPW syndrome, and dis-cusses the underlying pathophysiological mechanism.
