BACKGROUND Although the electrophysiological mechanisms underlying self-sustaining atrial fibrillation (AF) are unclear, recent studies suggest that one requirement for reentry, slow conduction, is frequently present in patients with AF. However, these observations limited to paroxysmal AF may not necessarily apply to chronic AF. Therefore,(More)
To compare and evaluate the bioavailability for intravenous fosphenytoin sodium with that of intravenous phenytoin sodium in Japanese subjects. In study 1, healthy Japanese male volunteers received a 30-min infusion of 375 mg fosphenytoin sodium or an equimolar dose of 250 mg phenytoin by a double-blind, crossover method. In study 2, other healthy Japanese(More)
Discordance between the (123)I-labelled 15-iodophenyl-3-R, S-methyl pentadecanoic acid (BMIPP) and (201)Tl findings may indicate myocardial viability (MV). This study compared dobutamine stress echocardiography (DSE) and single-photon emission computed tomography (SPECT) using the dual tracers for assessment of MV and prediction of functional recovery after(More)
The aim of the present study was to elucidate the effects of 4 different cardiovascular drugs on blood lactate levels during an intensive graded exercise test in 17 healthy male subjects. In acute studies, isosorbide dinitrate and nifedipine were used. In chronic studies, propranolol dihydrochloride and dilazep dihydrochloride were used. Oxygen uptake(More)
