Witryna13 lis 2024 · Conduction is how electrical impulses travel through your heart, which causes it to beat. Some conduction disorders can cause arrhythmias, or irregular … WitrynaAll tissues and fluids surrounding the heart have an abundance of ions, which means that they can act as electrical conductors. Consequently, the electrical currents generated in the myocardium are transmitted … dyspnea vs shortness of breath meaning

WitrynaAn impulse (action potential) that originates from the SA node at a relative rate of 60-100 bpm is known as a normal sinus rhythm. If SA nodal impulses occur at a rate less … WitrynaThe 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.
