Heart Node location and functions
purkinje fiber normal rate
20-40bpm
AV node normal rate
40- 60 bpm
SA node normal range
60-100 bpm
Purkinje fibers
Distribute electrical charge to cardiac muscle cells of ventricles, causing depolarization of cells, which results in both ventricles contracting together
AV node location
R atrium, R ventricle
SA node function
pace maker of the heart
purkinje fiber/av bundle location
AV bundle= IV Septum, purkinje fibers trace ventricles
AV node function
Acts as a gatekeeper and briefly delays impulses from the SA node, to allow the atria to contract completely and empty the blood into the ventricles.
SA node location
superior vena cava/R atrium
