First Degree AV Block
What happens to the PR interval in first-degree AV block?
What is prolonged; usually greater than 0.20 seconds.
Another name for Mobitz I.
(Hint: it starts with a W)
What is Wenckebach
What happens to the PR interval in Mobitz II?
The PR interval stays constant before the dropped beat.
What is another name for third-degree AV block?
What is Complete Heart Block.
What is asystole ANDDDDDDD what does asystole usually look like on an ECG?
What is no heart activity and that it looks like a flatline (patient DONE).
True or False:
Every P wave have a QRS complex in first-degree AV block.
What is True
What happens to the PR interval before a dropped beat ANDDDDDD what happens after the PR interval keeps getting longer?
What is the interval gets longer then the QRS complex is dropped.
(Acceptable answer: Normal, Long, Longer, Dropped)
What happens when an impulse is blocked?
What is QRS complex is dropped.
True or False:
The Bundle of His is getting electricity.
What is False
Why is asystole a cardiac arrest rhythm?
What is the heart has no useful electrical activity.
Where does the electrical impulse normally originate?
What is the SA Node
What part of the heart is commonly involved in Mobitz I?
What is AV Node
Name all the different names for Mobitz II.
What is 2nd degree type II and AV Block II
What happens to the PR intervals?
They have no consistent relationship because the atria and ventricles are beating independently.
True or False:
Normal P waves and QRS complexes are present in asystole.
What is False, AINT NOTHING THERE?!?!?!?
Is the rhythm usually regular or irregular in first-degree AV block?
What is usually regular.
What pattern is commonly seen in Mobitz I?
What is Normal, Long, Longer, Dropped
What is the major difference between Mobitz I and Mobitz II?
Mobitz I has progressively longer PR intervals; Mobitz II has constant PR intervals with sudden dropped QRS complexes.
How is third-degree AV block different from second-degree AV block?
In second-degree block, some impulses still conduct. In third-degree block, no atrial impulses conduct to the ventricles.
Put these in order from "not really worried bout it" to "OH GET THE DOCTOR STATTTTTTTTTTT AHHHHHHHH"
Wenckebach, Asystole, AV Block II, First-degree, CHB (3rd).
What is 1st degree, Wenckebach, AV Block II, CHB, Asystole.
(Acceptable Answer: First-degree, Mobitz I, Mobitz II, Third-degree, Asystole)
What makes first-degree AV block different from second-degree AV block?
What is every impulse gets through, but conduction is delayed.
How does Mobitz I differ from first-degree AV block?
Mobitz I has dropped beats, while first-degree AV block has no dropped beats.
Why is Mobitz II clinically REALLY dangerous?
It can turn into third-degree AV block.
What does “AV dissociation” mean?
The atria and ventricles beat independently.
The P waves and QRS complexes are both present, but they do not match up. The atria and ventricles are beating separately. What rhythm is this?
What is 3rd Degree AV Block
(Acceptable Answer: Complete Heart Block)
