1 paź 2023 · Action potentials in ventricular myocytes trigger the calcium (Ca 2+) entry necessary for their contraction. Their synchronicity, characteristic shape and length all help protect these cells against abnormal electrical activity. When these protective mechanisms go wrong, it can be potentially life threatening.
17 sie 2023 · The cardiac conduction system is a network of specialized cardiac muscle cells that initiate and transmit the electrical impulses responsible for the coordinated contractions of each cardiac cycle.
24 sie 2022 · SeisWind® 3D is designed to offer an efficient data acquisition footprint with the highest resolution to enable detailed ground modelling and interpretation of near surface geology for the safe development of offshore projects.
30 paź 2023 · This article will discuss the phases of the cardiac cycle and the underlying physiological principles that govern the process. There will be a brief review of the conducting system of the heart, as well as discussion of the disorders that affect the cardiac cycle.
24 wrz 2020 · Single-cell and single-nucleus RNA sequencing are used to construct a cellular atlas of the human heart that will aid further research into cardiac physiology and disease. Cardiovascular...
17 lip 2023 · Revisions: 31. format_list_bulleted Contents add. In the heart, electrical impulses are generated by specialised pacemaker cells and spread across the myocardium in order to produce a co-ordinated contraction in systole. An action potential generated is generated by a change in the potential difference between the inside and outside of the cell.
