Spatiotemporally Controlled Cardiac Conduction Block Using High-Frequency Electrical Stimulation
BACKGROUND Methods for the electrical inhibition of cardiac excitation have long been sought to control excitability and conduction, but to date remain largely impractical. High-amplitude alternating current (AC) stimulation has been known to extend cardiac action potentials (APs), and has been recently exploited to terminate reentrant arrhythmias by producing reversible conduction blocks. Yet,...
متن کاملAsymmetric Rectangular Waveform in Stimulation with High Frequency Alternating Current Reduces the Threshold for Neural Conduction Block
Introduction Abnormal neural impulses in the nervous system may lead to various diseases and disabilities. High frequency alternating currents (HFAC) has been used to block the propagation of such impulses and improve the symptoms or disabilities. The technique is safe, reversible, and relatively selective, and its reliability, the optimum stimulation parameters, and elimination of the onset re...
متن کاملElectrical conduction block in large nerves: high-frequency current delivery in the nonhuman primate.
Recent studies have made significant progress toward the clinical implementation of high-frequency conduction block (HFB) of peripheral nerves. However, these studies were performed in small nerves, and questions remain regarding the nature of HFB in large-diameter nerves. This study in nonhuman primates shows reliable conduction block in large-diameter nerves (up to 4.1 mm) with relatively low...

متن کاملSimulation of Neural Impulses Propagation Block by High-frequency Simulation
Electrical stimulation of a neural fibre is an alternative treatment of many neurological diseases, where conventional treatment procedures have undesirable side effect. Development of electrical stimulation technique suitable for reversible block propagation of pathological neural impulses is a challenging task. In this article, we have analyzed possibility of neural impulse propagation blocki...
