Action Potential of the Fish HeartWe analyze ion channel composition, functional properties of ion channels and drug sensitivity of sarcolemmal ion currents of the zebrafish heart to see how well they correlate with those of the hu…" [more]...

The time course of this change is similar to that of the action potential duration in ventricle following a change in stimulation frequency. These changes of the e.c.g. are probably not due to slow alterations of neural or hormonal factors extrinsic to the heart. In the whole heart, the ...
Each heart beat or contraction is initiated by generation of an action potential in the SA node; the electrical impulse spreads over both atria, causing them to contract, and on to the atrioventricular (AV) node. From the AV node it spreads through the bundle of His and down the Purkinje ...
Contraction of the cardiac muscle of the heart is initiated and controlled by an electrical stimulus called the cardiac action potential. It is a small (∼0.1 V) and transient (0.15–3.0 s) change of voltage across the cell membrane. This change in voltage results from the passage of vari...
The ECG and transmembrane action potentials of the ventricular cells of 12 mongrel dogs at various heart rates under pentobarbital anesthesia and spontaneous breathing were simultaneously recorded. After statistical analysis of the records of 139 units, quantitative relationship between action potential durati...
The casting is terrific but the character is underwhelming and not explored to his potential. Christoph Waltz’s limited appearance as an imprisoned Blofeld is great, and double agent Logan Ash (Billy Magnussen), and scientist Obruchev (David Dencik) prove quality secondary villains. The storyline...
This premise has been mined many times before for its dramatic potential, with the most obvious parallel being 2002 Hong Kong thriller Infernal Affairs. However, the key to Sleeping Dogs is that it’s not a homage to thrillers – it’s a homage to action flicks. … firing from behind ...
Scarlet Nexusis an action-adventure game set in an alternate reality of the near future in which humans have gained extrasensory superpowers. This world is an exciting and somewhat unnerving look at a potential alternate reality for humanity and is really interesting in terms of exploration. While...
a心脏好比电源,无数心肌细胞动作电位变化的总和可以传导并反映到体表 The heart is just like the power source, the innumerable cardiac muscle cell action potential change sum total may conduct and reflect the body surface[translate]
