Cardiac muscle has some similarities to neurons and skeletal muscle, as well as important unique properties. Like a neuron, a given myocardial cell has a negative membrane potential when at rest. Stimulation above a threshold value induces the opening of voltage-gated ion channels and a flood of cations into the cell. The positively charged ions entering the cell cause the depolarization characteristic of an action potential. Like skeletal muscle, depolarization causes the opening of v… 網頁2024年6月7日 · Both SCN5A [] and GJA5 [] have been implicated in inherited forms of progressive cardiac conduction disease or Lev-Lenegre disease [77,78], which is characterized by fibrosclerotic degeneration of the His-Purkinje system.

網頁The period of time that begins with contraction of the atria and ends with ventricular relaxation is known as the cardiac cycle ( Figure 19.3.1 ). The period of contraction that the heart undergoes while it pumps blood into circulation is called systole. The period of relaxation that occurs as the chambers fill with blood is called diastole. 網頁2024年10月5日 · The cardiac conduction system comprises the following structures in order: SA node, internodal pathway and Bachmann’s bundle, AV node, bundle of His, …
