BACKGROUND The circuit of atrioventricular (AV) nodal reentrant tachycardia may include perinodal atrial myocardium. Furthermore, in patients with dual AV nodal pathways, the atrial insertion of the slow pathway is likely to be located near the ostium of the coronary sinus, caudal to the expected location of the AV node. The present study was designed to evaluate the safety and efficacy of sele...

PURPOSE To investigate the slow and fast rod signals of the scotopic 15-Hz flicker ERG in patients with molecularly confirmed Stargardt disease type I (STGD1). There is evidence that these slow and the fast rod ERG signals can be attributed to the rod bipolar-AII cell pathway and the rod-cone coupling pathway, respectively. METHODS Twenty-seven patients with STGD1 with mutations in both allel...

INTRODUCTION The care for patients with a proximal femoral fracture has been dramatically overhauled with the introduction of 'fast track' protocols and the British Orthopaedic Association guidance in 2007. Fast track pathways focus on streamlining patient flow through the emergency department where the guidance addresses standards of care. We prospectively examined the impact these protocols h...

Electrophysiological evidence suggestive of dual atrioventricular (A-V) nodal pathways is presented in two patients with normal P-R interval and reentrant paroxysmal supraventricular tachycardia (PSVT). His bundle recordings and atrial stimulation were used to obtain this electrophysiological evidence. Refractory periods were measured with the atrial extra-stimulus technique. Plotting of H,-H2 ...

Abstract Introduction The ‘fast-track’ pathway to pancreatic resection is a straight surgery approach that avoids potentially harmful preoperative biliary drainage. A possible criticism the shortened time span from diagnosis makes it more difficult for patients adjust their new and mentally prepare surgery. emotional impact has on never been assessed. This study evaluated patient satisfaction o...

To elucidate differences in conduction properties among the normal atrioventricular (AV) node and the antegrade fast and slow dual AV nodal pathways (DAVNPW), AV nodal conduction curves were analyzed quantitatively in 38 patients. Eighteen patients had antegrade DAVNPW with AV nodal reentrant tachycardia (AVNRT) (dual pathways group) and the remaining 20 had smooth AV nodal conduction curves, w...

PURPOSE To study the slow and fast rod signals of the scotopic 15-Hz flicker ERG in patients carrying mutations in the NYX gene, which has been recently identified as the cause of the complete form of congenital stationary night blindness, CSNB1. METHODS Twenty eyes of 11 patients with CSNB1 who had nondetectable standard ERG rod b-waves were involved in the study. Scotopic ERG response ampli...
