Epicardial mapping and vectorcardiography in a child with type A WPW syndrome identified premature activation near the endocardium of the basal left ventricle, precluding surgical interruption.
Case Report (n=1)
Electrocardiographic and epicardial mapping studies are reported in a child with an atrial septal defect and a variant of type A Wolff-Parkinson-White (WPW) syndrome. The vectorcardiogram suggested a posterior area of early activation and this was confirmed by epicardial mapping studies. Premature activation apparently occurred from a site near the endocardium of the basal region of the left ventricle and surgical interruption could not be planned on the basis of data provided by epicardial mapping. The role of vectorcardiography in assessing patients with the WPW syndrome is discussed.
Neutze et al. (Sat,) conducted a case report in Atrial septal defect and a variant of type A Wolff-Parkinson-White (WPW) syndrome (n=1). Electrocardiographic and epicardial mapping was evaluated on Identification of early activation site. Epicardial mapping and vectorcardiography in a child with type A WPW syndrome identified premature activation near the endocardium of the basal left ventricle, precluding surgical interruption.
