BACKGROUND Fetal tachycardia may cause hydrops fetalis and lead to fetal death. No unanimity of opinion exists regarding the optimum treatment. This study evaluates our experience with transplacental sotalol therapy to treat fetal tachycardias in terms of safety and efficacy. METHODS AND RESULTS The charts of 21 patients who were treated with sotalol for(More)
BACKGROUND Fetal tachycardia complicated by ventricular dysfunction and hydrops fetalis carries a significant risk of morbidity and mortality. Transplacental digoxin is effective therapy in a small percentage, but there is no consensus with regard to antiarrhythmic treatment if digoxin fails. This study evaluates the safety, efficacy, and outcome of(More)
This paper presents an operating strategy for high-speed switched reluctance (SR) generators employed in exhaust gas energy recovery systems. The machine is operated in “single pulse” mode, and a parametric study of the control angles is performed to analyze the machine operation. It is shown that, for given speed and power, optimum sets of(More)
This paper describes a flexible modelling technique for the dynamic simulation of a switched reluctance machine employed in an automotive turbo-electric application to recuperate electrical energy. Due to the increasing numbers of electrically driven ancillaries and associated electrical load on the vehicle, a model which can be readily employed in a(More)
OBJECTIVE The purpose of this study was to determine whether Doppler velocimetry of the ductus venosus (DV) predicts adverse perinatal outcome in congenital heart disease (CHD). METHODS We conducted a retrospective cohort study of all pregnant women undergoing fetal echocardiography for CHD in a single perinatal center during a 2-year period. We compared(More)
OBJECTIVE To determine the contribution of the prenatal ultrasound diagnosis of structural congenital heart defects to the care of patients requiring surgery for their condition in the neonatal period. DESIGN Retrospective. METHOD During the period January 1991-June 1999, data were collected from two groups of children. One group had a structural heart(More)
