the ECG after induced paralysis. The V3 to V5 of figure 1 B ECG had elevation of the isoelectric line precedes the QRS, followed by a sharp R wave and then convex ST-segment elevation with wide T(U) wave inversion, which are typical Spike-Helmet...
heart disease, sleep apnea and other sleep disorders, genetics, metabolism, and nutrition, medical scientists have not been able to determine its exact cause. Medical opinion appears to favor an impairment of the electrical pathways and specialized muscle fibers that contract the heart. It is widely...
The ether-a-go-go-related genes (erg) are expressed in tissues other than heart and brain, in which human erg (HERG) K+ channels are known to regulate the repolarization of heart action potentials and neuronal spike-frequency accommodation. We provide evidence that erg1 transcripts and ERG pr...
Note: small, spike-like signals that occur with or without related exit to the ventricle producing PVCs. RVT = right ventricular; HRA = high right atrium; HBE1 and HBE2 = His bundle recording catheters; RVOT uni = right ventricular outflow tract unipola; AORT ablation =...
A family member confirmed to Wall Street On Parade that Salais died of a heart attack on the same evening the report of distress went in to the police. The incidence of heart attack or myocardial infarction among men aged 20 to 39 is one half of one percent of the population, a...
The mean values of spike number (Bin is 5 s) were normalized with the average of first min as 1. Values are shown as mean ± SEM. ∗p < 0.05; ∗∗p < 0.01; ∗∗∗p < 0.001; ∗∗∗∗p < 0.0001 by unpaired t test in (B) and (D) or two-way ANOVA followed...
This indicates that these rates of PMCA activation by Ca2+are correlated with the speed of Ca2+concentration decay after a Ca2spike in the cells in which these variants of PMCA are expressed. The results suggest that the type of PMCA expressed will correspond with the speed of Ca2+signals in...
The second suggested cascade involves a catecholamine spike causing reflex cardiac effects, including increased cardiac preload and afterload; the increase in ventricular inotropy, dromotropy, and chromotropy; and increased cardiac irritability leading to arrhythmias. These reflex cardiac effects may lead ...
Thermal Imaging (Infrared-Imaging-IRI) is a promising new technique for psychophysiological research and application. Unlike traditional physiological measures (like skin conductance and heart rate), it is uniquely contact-free, substantially enhancing i
