What is the flow of conduction in the heart? - Answer-SA Node --> AV Node --> Bundle
of His --> Purkinje fibers
Identify the parts of the conduction system - Answer-Left side: SA node, AV node, Right
bundle branch
Right side: Bundle of His, Left bundle branch, Left anterior division, Left posterior
division
In which AV block should we use Atropine with caution? - Answer-2nd degree TYPE 2
What is the special quality of the heart in relation to other muscles in the body? -
Answer-The heart generates its own electrical impulses
What is the normal HR when the SINUS node is in charge of heart conduction? -
Answer-60-100 bpm
What is the normal HR when the AV node is in charge of heart conduction? - Answer-
40-60 bpm
What is the normal HR when the Purkinje Fibers is in charge of heart conduction? -
Answer-20-40 bpm
What does the P-wave represent? - Answer-Atrial depolarization
What does the QRS complex represent? - Answer-Ventricular depolarization
What does the T wave represent? - Answer-Ventricular repolarization
Why is there no wave representing atrial repolarization? - Answer-Atrial repolarization is
covered by the ventricular depolarization wave
