The atrial depolarization spreads to the atrioventricular (AV) node, and passes through the bundle of His to the bundle branches/Purkinje fibers. The SA node, which develops during the fifth week, initially develops in the sinus venosus and then is incorporated into the RA. The AV node arises slightly superior to the endocardial cushions. Fibres forming the bundle of His develop from fast-conducting ventricular myocardium while the SA and AV nodes are formed from the slow-conducting myocardium of the inflow tract and AV canal.

Normal excitation originates in the sinoatrial (SA) node, then propagates through both atria (internodal tracts shown as dashed lines). The atrial depolarization spreads to the atrioventricular (AV) node, passes through the bundle of His (not labeled), and then to the Purkinje fibers which make up the left and right bundle branches; subsequently all ventricular muscle becomes activated. SA node to the purkinje fibers c.

The nurse is preparing to administer adenosine (Adenocard) 6 mg IV. Available is 6 mg When the SA node sends out an electrical impulse, the first place it goes is to the AV node. While the SA node sets the rhythm of your pulse, the AV node sets the rhythm of your heart contractions. It delays the signal on its way to the ventricle, giving the atrium time to contract first.

The SA nodes beats the fastest followed by the others as said. Node AV kemudian mengirimkan impuls ke bundel atrioventrikular ke ventrikel. Pengaturan sinyal listrik oleh AV node memastikan bahwa impuls listrik tidak bergerak terlalu cepat, yang dapat menyebabkan fibrilasi atrium. Pada fibrilasi atrium, atrium berdenyut tidak teratur dan sangat cepat dengan kecepatan antara 300 hingga 600 kali per menit.
