Impulse generation in heart
Did you know?
WitrynaAbnormal impulse formation can cause arrhythmias by the following two mechanisms: Increased or abnormal automaticity Triggered activity Increased or abnormal automaticity As discussed in Chapter 1 there are several structures in the heart that possess automaticity (i.e ability to depolarize spontaneously). These structures are as follows: Witryna• Contraction of the heart is based on the generation and conduction of the cardiac impulse. • Pacemaker cells can generate an impulse without any external stimulation, due to changes in electrolyte concentration inside and outside the cell. • The cardiac impulse is primarily generated from pacemaker cells in the SA

Cells in the SA node can spontaneously generate an electrical impulse, which transmits to perinodal ... ardyanna ducusinWitrynaThe heart's conduction system is composed of a network of excitable cells that transmit electrical impulses, resulting in organized and rhythmic contractions. Abnormalities in impulse generation and conduction are responsible for the development of arrhythmias. ardyan chandra dwi anggoroWitryna5 lip 2024 · A reentry arrhythmia is a self-sustaining cardiac rhythm abnormality in which the action potential propagates in a manner analogous to a closed-loop circuit. It is a disorder of impulse conduction and is discrete from disorders of impulse generation such as automaticity or triggered activity. ardyansah dan zulaikha 2014WitrynaThe cardiac conduction system coordinates the heart’s electrical activation.
