Late management after cardiac arrest

Question 1

Narrow complex tachycardia causes

Answer 1

sinus tachycardia
AF
atrial flutter
focal atrial tachycardia
AVNRT
AVRT

Question 2

Broad complex tachycardia causes

Answer 2

ventricular tachycardia
‘SVT’ with aberration
pre-excited tachycardia
pacemaker-associated tachycardia

Question 3

How does ventricular tachycardia present on an ECG?

Answer 3

no P waves
regular QRS complexes
broad QRS complexes - seen in all 12 leads
no identifiable T waves
slurred initiation of QRS

Question 4

What causes fast, irregular and broad (FBI) tachycardia?

Answer 4

atrial fibrillation with accessory pathway

Question 5

Possible causes of collapse

Answer 5

cardiac
cardiovascular
catastrophic vascular event
neurological
psychogenic

Question 6

What tachycardic events can cause collapse?

Answer 6

ventricular tachycardia
ventricular fibrillation
polymorphic ventricular tachycardia/Torsades de Pointes

Question 7

What bradycardic events can cause collapse?

Answer 7

AV block
SA block

Question 8

What cardiac underlying causes are there for collapse?

Answer 8

ischaemic heart disease
cardiomyopathy
structural heart disease
ion channel abnormalities

Question 9

What is Brugada syndrome?

Answer 9

affects way electrical signals pass through heart
can cause tachy arrhythmias

Question 10

Causes of long QT syndrome

Answer 10

drugs: amiodarone, tricyclic antidepressants, antibiotics, fluconazole, erythromycin, metoclopramide, quinidine, haloperidol, ondansetron, SSRIs

genetic (K or Na channel mutations):Jervell and Lange-Nielson syndrome (associated with deafness), Romano Ward syndrome

myocardial disease

electrolyte abnormality: hypocalcaemia, hypokalaemia, hypomagnesaemia
