Sentence examples for electrical impulse propagation from inspiring English sources

Peripheral nerve injury may lead to neuropathic pain and cause a markedly increase expression of growth associated protein-43 (GAP-43) in the spinal cord and dorsal root ganglion, local anesthetics blocking electrical impulse propagation of nerve fibers may also affect the expression of GAP-43 in the spinal cord and dorsal root ganglion.

We investigated short-term effects of particulate matter ≤ 2.5 μm in aerodynamic diameter (PM2.5) and ozone (O3) on cardiac electrical impulse propagation and repolarization as recorded in surface electrocardiograms (ECG).

Electrical impulse propagation is crucial for the synchronous contraction of the myocardium.

As in humans, our mice displayed high incidence of AV conduction blocks, which was accompanied by a marked prolongation of the infra-Hisian AV time indicating reduced electrical impulse propagation in the Purkinje fiber network.

Although the presence of a Purkinje system changes activation sequences, which will alter some of the effects seen during single-site pacing in this study, the absence of fast electrical impulse propagation through the Purkinje system allows one to dissect the effects of trabeculae-mediated breakthroughs during pacing, which represents a novel finding.

A variety of etiological factors can lead to sick sinus disease (SSD), a collection of disorders defined by abnormal electrical impulse formation and propagation from the SAN.

Here we show that propagation of the electrical impulse is significantly slowed in the right ventricle of ZDF rats compared to ZDL rats.

In the present study, we found no change in cell dimensions, ruling out that atrophy or hypertrophy causes the observed changes in the propagation of the electrical impulse.

The cardiac voltage-gated Na+ channel Nav1.5, encoded by SCN5A gene, determines the upstroke velocity of the action potential and, in conjunction with gap junction channels and the organization of the collagenous skeleton, controls the propagation of the cardiac electrical impulse.

Furthermore, redistribution and regulation of gap junction proteins (connexins) alter the physiological anisotropic ratio, which causes abnormal impulse propagation, thus enabling reentrant electrical activity [ 13].

Despite the rapid propagation (3 4 m/s) of the electrical impulse through the conduction tissue, activation of the ventricles occurs over a certain amount of time.
