1

What speed should an ECG be performed at?

25mm/sec

2

What is the correct location of the V5 electrode

5th intracostal space, Mid-clavicular line

3

What is the correct location of the V2 electrode

4th intracostal space, Left sternal edge

4

What is the rate?

 

 

140-160 (300/2 large squares)

5

What does the P wave represent?

Atrial Depolarisation

What is the rate?

70-80 (13 complexes x 6)

7

What is the diagnosis?

Atrial Fibrillation (Irregularly irregular with no P waves)

8

What is the diagnosis?

Left Axis Deviation (I and III are leaving / Lead I is +ve and lead aVF is -ve)

9

What is the diagnosis?

1st Degree Heart Block (prolonged and fixed P-R Interval)

10

Which lead is this?

Lead II

11

What is the diagnosis?

High rate, regular but wide complexes)

12

What is the diagnosis?

Sinus Tachycardia (Normal P-QRS-T waves but bad baseline)

13

What does the T wave represent?

Ventricular Repolarisation

14

What is this Rhythm?

Ventricular Fibrillation (Wide and irregular complexes)

15

What is this lead?

aVR

16

What is the diagnosis?

Right Axis Deviation (I and III are returning / Lead I is -ve and lead aVF is +ve)

17

What is the diagnosis?

Second Degree HB –Mobitz I (elongating P-R interval with dropped beat)

18

What is the diagnosis?

Normal Sinus

19

What is the diagnosis?

P.E - Right heart strain - SIQIIITIII – Deep S and Q and TWI

20

What are the causes of RAD?

RBBB, Lateral MI, RVH

21

What is the diagnosis?

RBBB – V1 - MoRRoW

22

What is the diagnosis?

LBBB (V1 – WiLLiaM)

23

What colour is this lead?

Green (RIDE YOUR GREEN BIKE in clockwise order from right hand)

24

What is the diagnosis?

Pericarditis (Widespread saddle ST elevation)

25

What does a deep & wide Q wave indicate

Old Ischemia

What is the abnormality?

WPW (Short PR interval and delta wave)

29

What is the diagnosis?

30

What does an abnormally deep S wave and tall R wave indicate?

Left Ventricular Hypertrophy (LVH)

31

What is the diagnosis?

Inferior STEMI (ST elevation in II, III and aVF)

32

What is the upper limit of the PR Interval?

Over 5 small squares/0.2 seconds

33

What is the diagnosis?

Hyperkalaemia (Tall T waves in all leads)

34
