OBJECTIVE: The JT interval of the myocardial repolarization time can be divided into Jpoint to T-peak interval (JTp) and T-peak to T-end interval (Tpe). It is well known that the JT interval is dependent on the heart rate, but little is known rega...
Restrictive cardiomyopathy (RCM) is a rare myocardial disease with an impaired diastolic function and poor prognosis. Almost all RCM patients are reported to have abnormal P-waves due to atrial overloading. This study aimed to reveal the character...

BACKGROUND: T-wave inversion (TWI) is not considered useful for diagnosing pediatric arrhythmogenic right ventricular cardiomyopathy (ARVC), because right precordial TWI in ARVC resembles a normal juvenile pattern. OBJECTIVES: The aims of this stu...

Little is known whether 2-g/kg IVIG is necessary for older children with Kawasaki disease (KD), because they could have more complications and financial burden. The purpose of this study was to compare outcomes between high- and low-dose IVIG in K...

The effects of nitroglycerin on cerebral hemodynamics in 6 preterm, infants with left ventricular (LV) afterload-mismatch status were evaluated by using near-infrared spectroscopy (NIRS).
Oxygenated Hb (O(2)Hb), deoxygenated Hb (HHb) and normalize...

Background: We hypothesized that patients with atrial (ASD) and ventricular septal defects (VSD) have similarly reduced heart rate variability (HRV) since both defects cause similar increases in pulmonary blood flow and right ventricular filling p...

Developmental care has been demonstrated to improve several clinical outcomes. However, its effect on the autonomic nervous systems is not well documented.
We evaluated the changes of the state and the autonomic nervous activity in 12 preterm infa...

Respiratory vagal activity is expressed by heart rate variability (HRV) at approximately 1 month of age in premature low-birth-weight infants (PLBWI). However, the autonomic inputs into the sinus node (SAN) and atrioventricular node (AVN) in PLBWI...
