When such a ventricular depolarization is superimposed on the T-wave, it is said that an R-on-T phenomenon has occurred.

Cardiac cycle - Wikipedia

WitrynaThe initial cardiac impulse, produced by pacemaker cells, originates in the sinoatrial (SA) node at the intersection of the right atrium and the superior vena cava. This action potential is the trigger of every cardiac cycle, initiating the atrial then ventricular contractions; it is henceforth responsible for the rhythmic beating of the heart. Witryna27 lip 2024 · Although all parts have the ability to generate action potentials and thus heart contractions, the sinuatrial (SA) node is the primary impulse initiator and … irish cattle breed codes https://infotecnicanet.com
