1

How does PE affect HR, BP, SaO2 and JVP

BP: normal
HR: tachycardic
SaO2: low
JVP: may be raised in large PE

2

Recall the management of PE

1. Oxygen
2. LMWH (tinzaparin, dalteparin)
3. Thrombolyse - but ONLY if haemodynamically unstable

3

Why can warfarin not be given immediately in PE?

It has an initially procoagulant effect

4

How do you determine whether there is axis deviation (either way) from an ECG, Amir Sam's way?

Look at leads I and II - if the QRS complexes are overall negative then there is deviation

5

How can you differentiate between right axis deviation and left axis deviation on ECG, Amir Sam's way?

Look at aVL:
If it is pos = LAD
If it is neg = RAD

6

What mnemonic should be used to identify bundle branch block on ECG?

WILLIAM MARROW
LBBB: W in V1, M in V6
RBBB: M in V1, W in V6
