bundle of His: (also, atrioventricular bundle) group of specialized myocardial conductile cells that transmit the impulse from the AV node through the interventricular septum; form the left and right atrioventricular 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.

The bundle of cardiac muscle fibers that conducts the electrical impulses that regulate the heartbeat, from the atrioventricular node in the right atrium to the septum between the ventricles and then to the left and right ventricles. Also called atrioventricular bundle. This is the dominant pacemaker’s (usually SA node) capability of suppressing all other slower pacing rates. The inherent rate is 60 to 100 b/min If the pacemaker is at the AV node or bundle of his, what is the inherent rate? 40-60 b/min If the pacemaker is in the bundle branches (i.e., ventricles) or purkinje fibers, what is the inherent rate? bundle of His: (also, atrioventricular bundle) group of specialized myocardial conductile cells that transmit the impulse from the AV node through the interventricular septum; form the left and right atrioventricular bundle branches Atrioventricular Bundle [Bundle of His] It is a continuation of the AV node and transmits the electrical impulse from the AV node to the Purkinje fibers of the ventricles.

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. AV node, SA node, bundle branches, AV bundle, Purkinje fibers. c. SA node, AV node, AV bundle, bundle branches, Purkinje fibers.

The fascicular branches then lead to the Purkinje fibers, which provide electrical conduction to the And that is the conduction system of the heart: the SA node creates the electrical impulse, it moves to the AV node and pauses for the atria to contract.

The AV node is continuous with the bundle of His, which gives off a left bundle branch at the top of the interventricular septum and continues as the right bundle branch. The left bundle branch divides into an anterior fascicle and a posterior fascicle. 2021-02-15 · The AV node contains only myocardial cells, no pacemaker cells. The bundle of His connects the AV node to the left and right bundle branches that control the contraction of the ventricles. The pacemaker cells within in the bundle can send electrical pulses at an accelerated rate of 40 to 60 beats per minute.

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.

The relatively slower conduction through this node allows time for the atria to contract and complete the filling of the ventricles. 4. The excitation wave travels rapidly through the bundle of His and then throughout the ventricular walls by means of the bundle branches and Purkinje fibers.
