Which Rhythm?
Which rhythm means the signal is just slow getting through?
What is First-Degree AV Block
Where does the heart's electrical signal normally start?
What is SA Node
In Mobitz I, does the signal eventually get dropped?
what is yes
What is another name for third-degree AV block?
What is Complete Heart Block.
How many beats per minute (BPM) does a person in Asystole have?
What is 0 BPM?
Which rhythm goes longer, longer, longer… then drops?
What is Mobitz I
What part slows the signal down before it reaches the ventricles?
What is AV Node
Another name for Mobitz I.
(Hint: it starts with a W)
What is Wenckebach or What is 2nd degree type 1
True or False:
The Bundle of His is getting electricity.
What is False?
Does a person in Asystole have a pulse?
What is No, they are in cardiac arrest with no blood flow?
Which rhythm has a normal-looking PR, then randomly drops?
What is Mobitz II or what is 2nd degree type 2
What happens when the signal gets stuck or slowed down?
What is AV BLOCK
What is the major difference between Mobitz I and Mobitz II?
Whst is mobitz I gets progressively longer before dropping a beat, while Mobitz II stays exact and fixed before suddenly dropping a beat.
What happens to the PR intervals?
What is they have no consistent relationship because the atria and ventricles are beating independently?
Why are there no QRS complexes on an ECG line during Asystole?
What is because there is zero electrical activity causing the ventricles to squeeze?
Which rhythm means the atria and ventricles are doing their own thing?
What is Third-Degree AV Block
What part of the electrical highway splits the signal into the left and right sides of the ventricles?
What is the bundle of branches.
Why is Mobitz II clinically REALLY dangerous?
What is it can turn into third-degree AV block.
How is third-degree AV block different from second-degree AV block?
What is in second-degree block, some impulses still conduct. In third-degree block, no atrial impulses conduct to the ventricles.
What are the top and bottom chambers of the heart doing during Asystole?
What is absolutely nothing, they are completely still and not squeezing.
Which rhythm looks like a flat line?
What is Asystole
What are the tiny, fast wires at the very end of the system that tell the muscle walls to squeeze?
Purkinje Fibers
If a patient is diagnosed with Mobitz II, will they most likely need a pacemaker inserted, or can they usually just go home and ignore it?
What is they will most likely need a pacemaker! (It's dangerous).
What does “AV dissociation” mean?
What is the atria and ventricles beat independently.
Can you shock a flatline (Asystole) with a defibrillator like in the movies?
No! Defibrillators reboot disorganized electricity. in Asystole, you need CPR only to kickstart the heart.
