BACKGROUND This study used monophasic action potential (MAP) to examine the effect of nicorandil, a K+ channel opener, on repolarization abnormalities induced by epinephrine in the LQT1 form of congenital long-QT syndrome in which the KvLQT1 mutation underlies the defect in the channel responsible for the slowly activating component of the delayed rectifier(More)
A new indicator dilution technique for measurement of cardiac output is described. Lithium chloride is injected via a central venous catheter and its dilution curve measured in arterial blood using a lithium-selective electrode. We assessed the lithium dilution cardiac output measurement (LiDCO) and a conventional thermodilution cardiac output measurement(More)
BACKGROUND The auditory evoked potential (AEP) index, which is a single numerical parameter derived from the AEP in real time and which describes the underlying morphology of the AEP, has been studied as a monitor of anesthetic depth. The current study was designed to evaluate the accuracy of AEPindex for predicting depth of sedation and anesthesia during(More)
BACKGROUND Idiopathic ventricular tachycardia (VT) is known to arise from the right ventricular (RV) and left ventricular outflow tracts (LVOT). However, reliable noninvasive methods to localize the optimum ablation site for VT have not been reported. METHODS AND RESULTS Body surface maps (BSM) and 12-lead ECGs were investigated in 35 VTs from the RVOT(More)
AIMS Differences in the sensitivity of the genotype of the congenital long QT syndrome to sympathetic stimulation have been suggested. This study compared the influence of sympathetic stimulation on continuous corrected QT (QTc) intervals between LQT1, LQT2 and LQT3 forms of the congenital long QT syndrome. METHODS AND RESULTS We recorded a 12-lead(More)
BACKGROUND There have been few studies comparing the response to asphyxia and the effectiveness of typical cardiopulmonary resuscitation (CPR) using exogenous epinephrine administration and manual closed-chest compression between total intravenous anaesthesia (TIVA) and inhalational anaesthesia. METHODS Twenty pigs were randomly assigned to two study(More)
The purpose of this study was to investigate the facial pattern of early childhood patient with temporomandibular joint (TMJ) dysfunction (clicking) occurred after anterior cross-bite correction. Chincap appliance was engaged in all cases, with or without minor intraoral mechano-therapy. Materials were consisted of lateral and postero-anterior cephalograms(More)
BACKGROUND We hypothesized that cross-clamping of the descending thoracic aorta (CcDTA) would result in significant changes in plasma propofol concentrations (Cp) proximal and distal to the cross-clamp. We investigated the effect of CcDTA on Cp centrally and distally, including the pulmonary artery and the cardiopulmonary bypass (CPB) cannula. METHODS The(More)
BACKGROUND The increase in remifentanil concentration during haemorrhagic shock and the difference between this effect and that for propofol are not fully understood. We investigated the influence of haemorrhage on the pseudo-steady-state remifentanil concentration in a porcine model and compared the changes with those for propofol. METHODS After infusion(More)
BACKGROUND Propofol is mainly metabolized in the liver, but extrahepatic clearance may also be important since systemic propofol clearance exceeds hepatic clearance. Recent reports suggest that the kidneys contribute to propofol elimination in humans and here we investigated renal elimination of propofol in a controlled animal study. METHODS Seventeen(More)
