Examples of atrioventricular (AV) node in the following topics:
-
- Closing of the atrioventricular valves produces a monosyllabic "lup" sound.
- The pulse reaches a second node, the atrioventricular (AV) node, between the right atrium and right ventricle, where it pauses for approximately 0.1 seconds before spreading to the walls of the ventricles.
- From the AV node, the electrical impulse enters the bundle of His, then to the left and right bundle branches extending through the interventricular septum.
- The signal is (b) delayed at the atrioventricular node before it is passed on to the (c) heart apex.
- Summarize the caridac cycle and explain the role of the SA node and the AV node in regulating the its rhythm
