We investigated changes in regional cerebral blood flow (rCBF) before and after weight gain in patients with restrictive anorexia nervosa (AN-R) in comparison with findings in normal subjects. We assessed resting rCBF using single photon emission computed tomography with technetium-99m hexamethylpropylene amine oxime in 12 AN-R patients and 11 controls.(More)
OBJECTIVE To perform ambulatory blood pressure monitoring (ABPM) in high school students and to compare the 24-hour values with casual blood pressure (BP). METHODS Ambulatory BP monitoring was carried out in 190 high school students, 15 or 16 years of age, with elevated casual BP during the first examination at school for hypertension; 66 had elevated(More)
Clinical characteristics and long-term prognosis of 163 children with ventricular arrhythmias without underlying heart diseases (78 with ventricular premature contractions (VPC group), 39 with ventricular couplets (CPLT group), and 46 with ventricular tachycardia (VT group)) were studied by Holter electrocardiographic monitoring (Holter ECG) and treadmill(More)
To investigate the possibility of estimating the right ventricular volume overload in atrial septal defect (ASD) by body surface mapping (BSM), 45 children with ASD were included in the present study. The breakthrough minimum (BTM) appeared later and more leftward in ASD subjects than in the normal controls. Neither the length of the delay in the appearance(More)
A 7-month-old boy presented with fulminant myocarditis. He was in cardiac shock and cardiac dysfunction progressed despite aggressive support. Extracorporeal membrane oxygenation (ECMO) was applied for 8 days and he recovered with mild dilated cardiomyopathy.
Eighty-three children were monitored by Holter electrocardiography for ventricular premature contraction (VPC), and the relationship between the preceding RR interval and the coupling interval was plotted using a two-dimensional RR interval plotting method. With this method, the slope (a) and standard deviation (SD) of the linear regression (Y = aX+b) were(More)
