Web17 de mar. de 2024 · Sinoatrial (SA) node. The SA node has the highest rate of depolarization in the whole system, so it can start the beat and set the pace for the whole heart; thus the term “pacemaker“. Atrial … WebThe sinoatrial node acts as the primary pacemaker – controlling the rate at which the heart beats (i.e. pace ‘making’) The SA node triggers roughly 60 – 100 cardiac contractions per minute (normal sinus rhythm) If the SA node fails, a secondary pacemaker (AV node) may maintain cardiac contractions at roughly 40 – 60 bpm
WebAn 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.

Web21 de oct. de 2024 · Sinoatrial node (SA node) is the normal pacemaker of the heart which gives regular electrical pulses to the heart muscles to beat. It is part of the electrical system of the heart. If the sinoatrial node fails, …
WebYour heart contracts (beats) when it receives an electrical impulse from your sinoatrial (SA) node. This signal is called heart conduction. The SA node is your body’s “natural pacemaker,” setting your heart’s rhythm. Heart conduction continues as the electrical signal moves to the atrioventricular (AV) node in your right atria.
