The main plurality of electrodes (A50, B51), and is configured to deliver a defibrillation pulse along the current path which is pre-determined in the portion of the first heart (RV32), the current path heart I defines a weak field region the second part of the of (LV34) during. One...
Electrical injury to the heart may cause long-term damage to conducting tissue: a hypothesis and review of the literature 来自 NCBI 喜欢 0 阅读量: 14 作者:NMK Robinson,DA Chamberlain 摘要: Electrical injury, particularly alternating current, may lead to disease of conducting tissue, myocardial ...
These cells send anelectrical signalto a special part of the brain. 然后这种细胞传输电子信号到大脑的特定部位. 互联网 As it travels, theelectrical signalcauses the heart to contract and pump blood. 而且这些电信号的传输也会引起心脏的收缩,从而达到心脏输送血液的目的. ...
Based on this effect, the Ultrasound Current Source Density Imaging has been introduced in 2008[30]. As its name suggests, this technique aims to detect sources of electrical current rather than electrical impedance itself. It is currently investigated for studying the heart using the cardiac action...
Artifacts, assumptions, and ambiguity: Pitfalls in comparing experimental results to numerical simulations when studying electrical stimulation of the heart Insidious experimental artifacts and invalid theoretical assumptions complicate the comparison of numerical predictions and observed data. Such difficultie.....

A both space and time adaptive algorithm is presented for simulating electrical wave propagation in the Purkinje system of the heart. The equations governing the distribution of electric potential over the system are solved in time with the method of lines. At each timestep, by an operator splitt...
Note slight slowing of heart rate with no change in blood pressure and single inspiratory gasp. Time lines indicate seconds. allow the monitoring of midpositional shifts in lung volume but did yield information regarding apnea or changes in tidal volume.
