QUIZ: What's the disease?

Question 1

ECG

No visible P waves
Irregular but normal looking QRS

Answer 1

Atrial fibrillation

Question 2

ECG

Rapid regular P waves, look a bit like the edge of a saw

Heart rate above 300

Answer 2

Atrial flutter

Question 3

ECG

Rapid, but normal QRS complexes which are followed immediately by P waves

Answer 3

AVNRT or AVRT

Premature P waves caused by premature depolarisation of atria due to re-entry

Question 4

ECG

Premature + broad QRS complexes that occur every second beat

Answer 4

Premature ventricular contraction

2:1

Question 5

ECG

Broad, unusual QRS complexes that look like this: /\/\/\/\/\

Occasionally you can see a P wave super-imposed onto a QRS

Answer 5

Ventricular tachycardia (as a specific disease

Question 6

ECG

Waxing and waning of QRS amplitude and width

Answer 6

Torsades de Pointes

Question 7

ECG

No decipherable QRS complexes
Chaotic, irregular rhythm

Answer 7

Ventricular fibrillation

Question 8

ECG

Bradycardia
The C1 lead appears to show an ‘M’ shaped QRS complex

Answer 8

Right bundle branch block

Question 9

ECG

Bradycardia
The C5 lead shows an ‘M’ shape in the tip of the peak of the QRS complex

Answer 9

Left bundle branch block

Question 10

ECG

Regular, normal speed heart rate
PR interval prolonged for 0.34 seconds

Answer 10

First degree heart block

Question 11

ECG

Intermittent recurrence of ‘dropped QRS complexes’ when a P wave is not followed by a QRS complex

In the build up to this there is increased prolongation of the PR interval

Answer 11

Secondary degree heart block

Mobitz 1 / Wenckebach

Question 12

ECG

Intermittent recurrence of ‘dropped QRS complexes’ when a P wave is not followed by a QRS complex

Answer 12

Secondary degree heart block

Mobitz 2

Question 13

ECG

QRS complexes are completely out of sync with P waves

Though the P waves appear to be regular

Answer 13

Third degree heart block

Question 14

ECG

Tachycardia
ST segment appears elevated

Answer 14

ST elevated MI

Question 15

ECG

The QR segment appears as a convex line rather than a straight one, on every 3rd beat

Answer 15

Wolff-Parkinson White syndrome

The convex line is caused by a delta wave

Question 16

Auscultation

The heartbeat sounds like: lub-dub-ta

BONUS: what is this murmur called?

Answer 16

Heart failure

S3 heart sound

Question 17

Auscultation

The heartbeat sounds like: a-lub-dub

BONUS: what is this murmur called?

Answer 17

Ventricular hypertrophy

The sound is generated by the atria having to contract extra forcefully

S4 heart sound

Question 18

Auscultation

2nd intercostal space
Right sternal border
A whistling sound can be heard

Answer 18

Stenosis of the aortic valve

Question 19

Auscultation

2nd intercostal space
Right sternal border
A blowing sound can be heard

Answer 19

Regurgitation of aortic valve

Question 20

Auscultation

2nd intercostal space
Left sternal border
A whistling sound can be heard

Answer 20

Stenosis of pulmonic valve

Question 21

Auscultation

2nd intercostal space
Left sternal border
A blowing sound can be heard

Answer 21

Regurgitation of pulmonic valve

Question 22

Auscultation

4th intercostal space
Left sternal border
A whistling sound can be heard

Answer 22

Stenosis of the tricuspid valve

Question 23

Auscultation

4th intercostal space
Left sternal border
A blowing sound can be heard

Answer 23

Regurgitation of the tricuspid valve

Question 24

Auscultation

5th intercostal space
Left mid-clavicular line
A whistling sound can be heard

Answer 24

Stenosis of mitral valve

Question 25

Auscultation

5th intercostal space
Left mid-clavicular line
A blowing sound can be heard

Answer 25

Regurgitation of the mitral valve
