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 ... 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.

WitrynaIn this article, the authors outline the key components behind the automated generation of the cardiac impulses and the effect these impulses have on cardiac myocytes. … WitrynaCCD is characterized by a delay in electrical impulse conduction at the atrial, nodal, and ventricular levels. Inherited forms of CCD may be secondary to congenital heart … WitrynaThe stimulus is typically a premature ventricular beat (i.e an ectopic beat from within the ventricles) or inappropriate stimulation from an artificial pacemaker. When such a ventricular depolarization is superimposed on the T-wave, it is said that an R-on-T phenomenon has occurred. diy glass aquarium building tips
