Heart conduction Flashcards
1
Q
Speed of conduction
A
Purkinje > atria > ventricles > AV node
“Patria vents VAN”
2
Q
Pacemakers
A
SA > AV > Bundle of His/Purkinje/Ventricle
3
Q
Conduction pathway
A
SA node -> atria -> AV node -> common bundle -> bundle branches -> Purkinje fibers -> ventricles
4
Q
SA node
A
Pacemaker inherent dominance with slow phase of upstroke
5
Q
AV node
A
100 msec delay
AV delay; allows time for ventricular filling
