The heart conduction system is made up of cells, nodes, and signals that help your heart to beat. In fact, the cardiac conduction system is responsible for our heart beating around 2.5 billion times during the average human lifespan. The conduction system, also called the cardiac electrical sy...
The heart has a complex electrical system which regulates the contraction and relaxation of its muscular wall. This enables the heart to function by receiving blood during relaxation and pumping it out with force to the lungs and other parts of the body. The rhythm of the heart beat is contro...
Electrical uncoupling and conduction block in the injured mammalian heartNot Availabledoi:10.1016/0022-2828(91)90920-HA. QueyroyL. TranquiJ. VerdettiJournal of Molecular and Cellular Cardiology
We revealed their close relationship with sympathetic innervation during cardiac conduction system formation. Our study thus provides new insights into the development and heterogeneity of the mammalian cardiac conduction system by revealing a new cardiomyocyte population with potential catecholaminergic endocrine...
These data provide a strong indication of the increased complexity of our hHO system and its close resemblance to fetal heart tissue. It should be noted that while our immunofluorescence and bulk RNA sequencing data suggest the presence of the cardiac cell types described above, these techniques ...
These complex electrical waveforms shown on Fig. 1 contain a significant amount of information on the functional state of the cardiovascular system. At the beginning of an auricular systole, a first wave (P) appears on the ECG related to the auricular depolarisation. Then follows the QRS ...

(anticipating increased day-time demand). Although this is attributed to a day-night rhythm in post-translational ion channel regulation in the heart’s pacemaker, the sinus node, by the autonomic nervous system, we investigated whether there is a day-night rhythm in transcription. RNAseq ...
(A) Schematic diagram of cryoinjury model showing transmural incisions and conduction pathways. Action potentials generated in the region proximal to the scar can be propagated to regions distal to the scar through active conduction through the myocyte pathway (myocyte), or by passive spread of ...
FIG. 14 shows in form of a block diagram a fifth embodiment of the device, used in a rate-responsive pacemaker. FIG. 15 shows how impedance in the heart varies during a heart cycle. FIG. 16 illustrates in the form of a coordinate system diagram the function of the fifth embodiment. ...
