Unlike Grant's previous albums, Heart In Motion contains … 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 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. 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. The AV node then "gathers" that … hypertension cpg 2018

Witryna5 lip 2024 · A reentry arrhythmia is a self-sustaining cardiac rhythm abnormality in which the action potential propagates in a manner analogous to a closed-loop circuit. It is a disorder of impulse conduction and is discrete from disorders of impulse generation such as automaticity or triggered activity.
