Electrophysiological Sensors In article number 2200342, Ryan Kaveh, Ana C. Arias, and co-workers present a fabrication method for rapidly producing low impedance, anatomically fit dry electrodes that do not require hydrogels. By using electroless copper gold plating with 3D printing, biocompatible can be optimized individuals at fraction of the cost existing vacuum deposition-based techniques.

Cellular and molecular events can be investigated using electrophysiological techniques. In particular, the patch-clamp method provides detailed information. In addition, the patch-clamp technique has become a powerful method for investigating the mechanisms underlying the effects of acupuncture. In this paper, recent researches on how acupuncture might modulate electrophysiological responses i...

PURPOSE OF REVIEW Brain MRI (diffusion tensor imaging and spectroscopy) and functional neuroimaging (PET, functional MRI, EEG and evoked potential studies) are changing our understanding of patients with disorders of consciousness encountered after coma such as the 'vegetative' or minimally conscious states. RECENT FINDINGS Increasing evidence from functional neuroimaging and electrophysiolog...

Sustained ventricular tachycardia and ventricular fibrillation are life-threatening arrhythmias with high rates of recurrence.1'2 Empiric antiarrhythmic drug therapy has a low success rate for preventing recurrences of these arrhythmias.3 Therefore, the choice of drug therapy has centered around two methodologies to predict drug efficacy: programmed ventricular stimulation with serial drug test...

Background. Information about electrophysiological characteristics and radiofrequency ablation of intra-atrial reentrant tachycardia has not been reported before. We proposed that induction and termination of intra-atrial reentrant tachycardia by atrial extrastimuli or rapid atrial pacing and resetting the response pattern by atrial extrastimuli during intra-atrial reentrant tachycardia could e...

The purpose of the following pilot study is to evaluate the possibility to detect the asymptomatic ischemic episodes which often precede dangerous events by means of endocardial signals. Intracardiac electrograms (IEGMs) have been detected in patients undergoing percutaneous transluminal coronary angioplasty (PTCA), a procedure during which ischemic episodes are induced. For 10 patients IECGs h...

OBJECTIVES To report our experience with intracardiac potassium chloride (KCl) injection as a method of feticide for severe congenital abnormalities beyond 24 weeks' gestation. METHOD A retrospective chart review. Patient demographics and types of fetal anomalies were analysed according to the groups that accepted or declined late termination of pregnancy (LTOP, ≥24 weeks) for severe congenit...

Over 75,000 antitachycardia devices (ATDs) have been implanted since initial Food and Drug Adrninistra-tion approval in 1985 and have yielded dramatic survival rates. These devices, although life-saving, rely principally on simple measures of the heart rate for arrhythmia detection. The ATDs are highly sensitive, but their low specificity of diagnosis results in episodes of inappropriate therap...

UNLABELLED Studies have reported compatibility between hearing and electrophysiological thresholds in the auditory brainstem response (ABR) with tone burst stimuli. AIMS to verify waves I, III, V and their latency times for tone bursts at 500, 1000, 2000 and 4000 Hz and at 80 dB HL, and to compare tone burst electrophysiological thresholds with those obtained from audiological and psychoacous...
