WitrynaRegulatory pathways overseeing cardiac impulse generation and conduction provide effective and safe pacing, and help maintain the rate according to the physiological … WitrynaThe normal electrophysiologic behavior of the heart is determined by ordered propagation of excitatory stimuli that result in rapid depolarization and slow repolarization, thereby generating action potentials in individual myocytes. Abnormalities of impulse generation, propagation, or the duration and configuration of individual cardiac action ...

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. Witryna12 mar 2024 · The cardiac electrical signal controls the heartbeat in two ways. First, since each electrical impulse generates one heartbeat, the number of electrical impulses …

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 … Witryna29 sie 2024 · After an electrical impulse is generated by the sinus node (located at the top of the right atrium), it spreads across both atria, causing these chambers to beat.
