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. WitrynaAn electrical stimulus is generated by the sinus node (also called the sinoatrial node, or SA node). This is a small mass of specialized tissue located in the right upper chamber (atria) of the heart. The sinus …

Additionally, Dr. Youdim suggests reducing the need to make decisions when possible. For ... Witryna1 gru 2002 · Abnormal impulse generations that can initiate cardiac arrhythmias are generally believed to originate from either automaticity or triggered activity . Triggered activity is so-called because unlike the spontaneous depolarisations of automaticity the impulse can only occur if it follows a previous action potential, i.e. it is said to be ...

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 ... WitrynaIt’s also known as your heart’s electrical system. Cells in the cardiac conduction system can generate electrical impulses and then distribute the signal throughout your heart. While all cells in your heart can conduct electricity, the cells in this system conduct it at very specific speeds.
