Cardiac causes

2

In a collapse, what mnemonic should you use for management?

ABCDEFG
Airway
Breathing
Circulation
Don't Ever Forget Glucose

3

Which type of heart murmur is most likely to cause collapse?

Aortic stenosis

4

In a collapse, what mnemonic should you use to guide your differential diagnosis?

3 Ps
Precipitating factor
Posture
Prodrome?
These are the 3 Ps of VASOVAGAL SYNCOPE

5

Recall 3 cardiac causes of collapse

Postural hypotension
Outflow obstruction
Arrhythmias

6

Recall 3 non-cardiac causes of collapse

Hypoglycaemia
Vasovagal syncope
Seizure

7

What are the 2 possible causes of cardiac outflow obstruction, and what investigation could reveal these abnormalities?

Hypertrophic Obstructive Cardiomyopathy
Aortic Stenosis
Echocardiogram

8

Recall 2 positive signs on examination of outflow obstruction

Ejection systolic murmur
Slow-rising pulse

9

Which arrhythmia does Amir Sam say might cause collapse?

Long QT syndrome causing ventricular tachycardia

10

How do you spot long QT syndrome on an ECG?

- Draw a horizontal line between the 2 R waves
- Draw a 2nd, vertical line halfway between the R waves
- If this line does not cross T wave = normal
- If the 2nd line intersects the T wave = long QT

11

Which electrolyte imbalances may cause long QT syndrome?

Hypokalaemia
Hypomagnesaemia

12

What is the first line in investigation for suspected long QT syndrome?

Cardiac monitor bed and 24 hour tape
