Caption: Figure 4: Pulse propagation characteristics inside dispersive media modeled by Maxwell-Garnet formula and described by linear filling factor function and depolarization
factor [N.sub.1] = [N.sub.2] = [N.sub.3] = 1/3: (a) reflectance and transmittance and (b) penetration depth spectra for different values of the initial value f(0).
2, the decrease in the rate of depolarization
of action potential slows intra ventricular conduction and increases the duration of QRS complex.
Among the techniques suitable to study molecular mobility in very viscous systems, dynamic mechanical spectroscopy, NMR spectroscopy, dielectric relaxation spectroscopy (DRS), and thermally stimulated depolarization
currents (TSDC) are the most frequently used.
Will Prime Minister Nikola Gruevski try to "fool" Europe again, regarding the implementation of conclusions adopted in Brussels for the depolarization
of courts, administration, police, media and other institutions?
(PR segment is the interval between the onsets of atrial depolarization
and ventricular depolarization
.) Prolonged action potential duration (amount of time that voltage remains above threshold) first occurred at 1 [micro]M BPM, and delayed atrioventricular conduction appeared at 10 [micro]M BPM.
In 2001, my group and two other laboratories independently reported that depolarization
of postsynaptic neurons causes endocannabinoid-mediated transient suppression of transmitter release from presynaptic terminals in the hippocampus and cerebellum.
Although the latter is primarily attributed to neuronal influences, decreased heart rate variability can also indicate alterations in ion channel currents that drive pacemaker depolarization
(Papaioannou et al.
Purpose/Hypothesis: The QT interval is an element of the electrocardiograph (ECG) tracing that includes ventricular depolarization
and repolarization and that provides clinical evidence regarding ventricular function.
The QT interval encompasses both depolarization
and repolarization of heart and was measured from the earliest Q- or R-wave onset to the end of T wave.
However, these dielectric measurements are not adequate because they do not reveal information on the polarization current, depolarization
current, and the conductivity variation.
The effects of CRF on neuronal excitability were mediated via activation of CRF2 receptors and a cationic channel to generate membrane depolarization
An additional atrioventricular ring has been designed to make fast depolarization
of the ventricles.
