A
10
Q
outline ECG changes in RBBB
A
MaRRooN
- M shape in V1
- N shape in V6
- N=Normal QRS, just a bit wider
(rSR= small rise, big drop, and even bigger rise)
11

outline ECG changes in LBBB
A
ViLLhelM
- V shape in V1
- M shape in V6
12
Q
outline the waves in the JVP and what they signify
A
- a wave= atrial systole
- c wave= tricupsid valve closing
- v wave= passive atrial filling
13
Q
in what instance would you have a raised JVP?
A
- RHF
- fluid overload
- SVC obstruction
- pericardial tamponade
- constrictive pericarditis
14
Q
in what pathology would large JVP A waves be seen?
A
- PHT
- Tricuspid stenosis
- Pul stenosis
15
Q
when would JVP a waves be absent?
A
AFib
