1
Q

1st degree heartblock ECG

A

PR interval constantly > 200ms (5 small squares)- no lost heart beats.

2
Q

1st degree heartblock treatment

A

None

3
Q

2nd degree heart block type 1 ECG

A

Progressive lengthening of PR w/ 1 actual loss of a QRS

4
Q

2nd degree heart block type 1 treatment

A

None

5
Q

2nd degree heart block type 2 ECG

A

Constant prolonged PR but there’s a randomly dropped QRS- can follow a fixed ratio block of 2:1 or 3:1

6
Q

2nd degree heart block type 2 treatment

A

may need pacing either temporarily or permanently

7
Q

3rd degree heart block ECG

A

no association bwt the p waves and QRS complexes

8
Q

3rd degree heart block treatment

A

needs pacing

9
Q

Right bundle branch block ECG

A

M in V1 and W in V6
RSR’ in V1, qRS in V6

10
Q

Left bundle branch block ECG

A

W in V1 and M in V6
rS in V, R in V6

11
Q

Bradycardia management

A

Atropine 500 mcg IV first line,
if unsatisfactory response- atropine up to maximum of 3mg, transcutaneous pacing, isoprenaline/adrenaline infusion titrated to response

12
Q

Atrial tachycardia ECG

A

abnormal/inverted p waves

13
Q

Atrial flutter ECG

A

Saw tooth pattern

14
Q

Atrial flutter treatment

A

control rate w/ a beta blocker

15
Q

Atrioventricualr nodal reentrant tachycardia ECG

A

Rapid, narrow QRS. Most common SVT

16
Q

Atrioventricular reentrant tachycardia ECG

A

Can get WPW syndrome- slurred upstroke in the QRS complex

17
Q

WPW management

A

radiofrequency ablation of the accessory pathway
Sotalol, amiodarone, flecainide

18
Q

Ventricular tachycardia causes

A

Congenital
Drugs eg Amiodarone, Sotalol, Chloroquine, Eryhtromycin
Hypocalcaemia, Hypokalaemia

19
Q

Ventricular tachycardia management

A

if adverse signs, immediate synchronised DC cardioversion. Drug therapy- Amiodarone ideally thru a central line

20
Q

Torsades de pointes management

A

IV magnesium sulphate

21
Q

Ventricular fibrilation ECG

A

Uncoordinated chaotic baseline, no identifiable features

22
Q

ventricular fibrillation management

A

unsynchronised DC cardioversion

23
Q

Supraventricualr tachycardia management

A

if haemodynamically unstable- always synchronised DC cardiovert
Vagal manouevres: Valsalva manouevre, carotid sinus massage.
IV adenoside rapid IV bolus of 6mg
