Jun-Hwa Lee, Yeo-Hyang Kim, Myung-Chul Hyun, Sang-Bum Lee
Clin Exp Pediatr. 2007;50(5):476-483.   Published online May 15, 2007
Purpose : The objective of this study was to assess ventricular function by tissue Doppler imaging (TDI) in children with congenital heart disease (CHD) who have been undergoing open heart surgery (OHS) using cardiopulmonary bypass. We tried to compare the parameters of tissue Doppler imaging before and after OHS in patients with congenital heart disease. Methods : This study was conducted...

Clin Exp Pediatr. 2007;50(5):462-468.   Published online May 15, 2007
Purpose : The purpose of this study was to analyze the changes of the late potential of Signal- averaged electrocardiography (SAECG) and Electrocardiography (ECG) parameters during follow up of those who had taken surgical repair of Tetralogy of Fallot (TOF). Methods : Nine patients who had taken surgical repair of TOF since 1985 checked SAECG and standard 12 leads ECG twice...
