A 15-year-old female with WPW syndrome and normal heart underwent an electrophysiology study for paroxysmal palpitations and syncope. Intravenous adenosine produced an unexpected response of QRS changes and advanced AV block. During isoproteronol infusion, short-lasting and poorly tolerated wide QRS tachycardia was inducible, but pacing maneuvers were not feasible during tachycardia to determin...

introduction: the functional effects of orexin-b on the calcium spikes and excitability of the neuronal soma membrane of garden snail, helix aspersa were studied. methods: conventional intracellular recording, under the current clamp conditions was performed to examine the effects of orexin-b on the configuration and electrophysiological properties of calcium spikes. results: application of ore...

a b s t r a c tintroduction: peripheral nerve injury is a common disorder and leads to permanent neurological defects. schwann cells have been shown to have nerve repair after being transplanted in peripheral nerve injury. the aim of this study was to determine the beneficial effect of allograft schwann cells on electrophysiological outcome after transection of the sciatic nerve in rats.methods...

Although the correspondence between functional-magnetic resonance imaging (fMRI) representations of the sensorimotor cortex and intraoperative electrophysiology (including somatosensory evoked potential, SSEP, recordings and direct cortical stimulation) has been reported, a similar correspondence between fMRI and intraoperative localization of the language-sensitive cortex is not as well establ...

OBJECTIVES The purpose of this study was to evaluate a new technique for sterilizing nonlumen electrophysiology catheters that uses hydrogen peroxide gas plasma. BACKGROUND The reuse of electrophysiology catheters may potentially result in a significant cost savings. While ethylene oxide sterilization appears to be safe and effective from a clinical standpoint, toxic ethylene oxide residuals,...

Dorland’s Illustrated Medical Dictionary in its 24th Edition (1965), describes the term “Electrophysiology” as “The Science of physiology in its relations to electricity; the study of the electric reactions of the body in health.” The ability of scientists to observe and record physiology’s electrical phenomena long preceded the understanding of the membranous ionic processes that are responsib...
