Current Opinion in Cardiology, 1993
Our understanding of pediatric arrhythmias continues to evolve through natural history studies of paroxysmal supraventricular tachycardia, the congenital long QT syndrome, and postoperative atrial and ventricular tachyarrhythmias. The influence of the autonomic nervous system on cardiovascular function may play a role in the sudden infant death ...

Abstract One important method that can be applied for gaining an understanding of the implementation of aesthetics in the brain is that of electrophysiology. Cognitive electrophysiology, in particular, allows the identification of components in a mental processing architecture.

The purpose of this chapter is to differentiate between the major categories of electrophysiological techniques and preparations, comparing the relative advantages, disadvantages, and common uses of each. We will start with a brief review of the physical principles that provide neurons their electrical characteristics.

The electrophysiology of the saccule
Pfl�gers Archiv European Journal of Physiology, 1972The Na+ concentration in saccular endolymph in guinea pigs was measured and found to be 3.2±0.6 mEqu/l with sodium specific electrodes. The saccular potential varied between −8 and +2.4 mV. Permanent anoxia resulting in the death of the animal caused the potential to fall by 15 mV and the Na+ concentration to rise to 40 mEqu/l in 30 min. Maintenance of

The electrophysiology of the utricle
Pfl�gers Archiv European Journal of Physiology, 1972The Na+ concentration in utricular endolymph of guinea pigs was measured with Na+ specific electrodes and found to be 12.6±5.8 mEqu/l. The utricular potential was 1.8±4.4 mV. Permanent anoxia resulting in the death of the animal caused the potential to fall by 15 mV and the Na+ concentration to rise at a rate of 0.4 mEqu/l per minute.

Electrophysiological recording techniques have been widely applied to study the functional role of neuropeptides. The present chapter focuses on the very often used techniques including whole-cell patch-clamp recording, sharp electrode intracellular recording, and extracellular field potential recording in slice preparation as well as in vivo animal ...

Electrophysiology of the Cochlea
Otolaryngologic Clinics of North America, 1975With careful techniques it is possible to demonstrate three electric potential regions of the inner ear: an intracellular negative potential, a high positive potential in the endolymph that appears bounded at the scala media side of the tectorial membrane rather than at the reticular lamina, and the extracellular spaces, which contain a fluid at near ...

The electrophysiologic characteristics of esmolol were studied in 14 patients. Ten men and 4 women, mean age 57 years, were electrophysiologically evaluated at baseline, and also at 4 to 8 minutes after the administration of a maintenance infusion of esmolol.

Cardiovascular Research, 1975
The effect of atropine on the refractory periods of the human atrium, A-V node, and His-Purkinje system was studied. The A-V node in man appears more sensitive to atropine than the atria as evidenced by a reduction in the effective and functional refractory periods of the A-V node without alteration of atrial conduction.

Dimensions of Critical Care Nursing, 2003
The purpose of this article is to provide an introduction to electrophysiology (EP) testing. The history and evolution of EP testing will be reviewed briefly. The indications for electrophysiology studies (EPS) testing, EP definitions and terminology, components of a basic EP procedure, and potential complications will also be presented.
