Answers | Verified | Latest 2024 Version
What is the flow of conduction in the heart? - ✔✔SA Node --> AV Node --> Bundle of His --> Purkinje
fibers
Identify the parts of the conduction system - ✔✔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? - ✔✔2nd degree TYPE 2
What is the special quality of the heart in relation to other muscles in the body? - ✔✔The heart
generates its own electrical impulses
What is the normal HR when the SINUS node is in charge of heart conduction? - ✔✔60-100 bpm
What is the normal HR when the AV node is in charge of heart conduction? - ✔✔40-60 bpm
What is the normal HR when the Purkinje Fibers is in charge of heart conduction? - ✔✔20-40 bpm
What does the P-wave represent? - ✔✔Atrial depolarization
What does the QRS complex represent? - ✔✔Ventricular depolarization
What does the T wave represent? - ✔✔Ventricular repolarization
Why is there no wave representing atrial repolarization? - ✔✔Atrial repolarization is covered by the
ventricular depolarization wave
