Cardiovascular Flashcards
1
Q
1st Degree Heart Block
A
R far from P then you have 1st degree
PR interval > 0.2 seconds
2
Q
2nd Degree Heart Block
A
Mobitz type 1
Longer, longer, longer, drop then you have Wenckebach
PR interval becomes progressively longer w/ each cycle then last P wave does not conduct to the ventricles
3
Q
2nd Degree Heart Block
A
Mobitz type 2
Some Ps don’t get through then you have Mobitz II
Normal P waves & consistent PR interval
Usually a set ratio 2:1 or 3:1
After the dropped QRS the next P arrives right on time
4
Q
3rd Degree Heart Block
A
Ps & Qs don’t agree then you have 3rd degree
AV dissociation
No correlation b/w P waves & QRS complexes
5
Q
EKG Leads
II, III, & aVF
A
Inferior (apical)
RCA
6
Q
EKG Leads
V1-V4
A
Anterior
LAD
7
Q
EKG Leads
I, aVL, V5-V6
A
Lateral
L circumflex
