ECG

Question 1

Name the arrhythmia

Answer 1

2nd degree AV block

(physiological - AV node stops depolarisation of ventricles every 3-4 beats, leading to a pause 2X R-R interval)

Question 2

Name the arrhythmia

Answer 2

Sinus block or arrest

(physiological - no P wave and variable R-R interval)

Question 3

Name the arrhythmia

Answer 3

Atrial fibrillation

Question 4

Name the arrhythmia

Answer 4

Atrial fibrillation

Question 5

Name the arrhythmia

Answer 5

Atrial premature complex

P wave occurs prematurely and is followed by a normal QRS

Question 6

Name the arrhythmia

Answer 6

Sinus bradycardia

Question 7

Name the arrhythmia

Answer 7

Sinus tachycardia

Question 8

Name the arrhythmia

Answer 8

Sinus block

Pause 2X R-R interval but no P wave present (unlike 2nd degree block)

Question 9

Name the arrhythmia

Answer 9

Sinus arrhythmia

R-R intervals are irregular, but every P leads to a QRS

Question 10

Name the arrhythmia

Answer 10

Atrial fibrillation

P waves are absent, R-R intervals irregular and f waves present

Question 11

Name the arrhythmia

Answer 11

Second degree AV block (Mobitz 1)

Pause for 2X R-R interval where P wave is not followed by QRS

Question 12

Name the arrhythmia

Answer 12

Ventricular premature complexes

T wave followed by premature QRS

Question 13

Name the arrhythmia

Answer 13

Ventricular tachycardia

Defined as 4+ VPCs
