The impulses then enter the base of the ventricle at the Bundle of His and then follow the left and right bundle branches along the interventricular septum. (90 msec) following SA nodal firing. After a delay at the AV node, the septum becomes activated (0.16 sec). All the ventricular mass is …
Figure 2. The conduction system of the heart. Left: Normal excitation originates in the sinoatrial (SA) node then propagates through both atria. The atrial depolarization spreads to the atrioventricular (AV) node, and passes through the bundle of His to the bundle branches/Purkinje fibers.

From a rising star in Scottish romance comes a breathtaking trilogy of forbidden passion, legendary heroes, and sacred bonds. In Maya Banks's Highlander
That AV node is pretty smart. So once that AV node allows that electrical impulse to pass through, it moves to the bundle of His, which is located just below that AV node, and from there it separates through the left and right bundle branches. This is a brief description of signal generation inside the heart.It briefly talks about SA node, AV node, Bundles of His and Purkinje fibers.

A latent pacemaker When the other foci (AV node, bundle of his, bundle branches, purkinje fibers) become the pacemaker, this is referred to as: Escape
Electrical signals arising in the SA node (located in the right atrium) stimulate the atria to contract.Then the signals travel to the atrioventricular node (AV node), which is located in the interatrial septum.After a delay, the electrical signal diverges and is conducted through the left and right bundle of His to the respective Purkinje fibers for each side of the heart, as well as to the
Since the right atrium is closer to the SA node, it depolarizes first, resulting in pumping action by the right atrium before the left atrium. At the AV node, the impulse is delayed to allow for the ventricles to fill up with blood. After the delay, the AV node sends the impulse to the Bundle of His and the Purkinje fibers.

Select all A. are responsible for creating the "lub" sound when closing B. 2021-04-20 The SA node excites the right atrium (RA), travels through Bachmann’s bundle to excite left atrium (LA). The impulse travels through internodal pathways in RA to the atrioventricular (AV) node. From the AV node, the impulse then travels through the bundle of His and down the bundle branches, fibers specialized for rapid transmission of electrical impulses, on either side of the SA node, AV bundle, AV node, bundle branches, Purkinje fibers e.
