16
Q

What stage of heart conduction is shown on:

a) P-wave
b) QRS complex
c) T-wave
d) PR interval
e) ST segment
f) QT interval
g) U-wave

A

a) atrial depolarisation
b) ventricular depolarisation
c) ventricular repolarisation
d) AVN delay (end of p-wave -> start of q-wave)
e) time between depolarisatoin and repolarisation
f) time taken for ventricular depolairsation and repolarisation
g) repolarisation of papillary muscles and purkinje fibres

17
Q

What wave on an ECG is not always present but shows repolarisation of papillary muscles and purkinje fibres

A

U-waves

18
Q

On an ECG, how many seconds is their in a small and a large box

A

Small -> 0.04s

Large -> 0.2

19
Q

How do you work out the rate in an ECG

A

300/(number of big sqaures between QRS complexes)

(obvs you know that one big sqaure is 0.2s)

20
Q

A broad QRS complex is a sign of what ECG abnormality

A

Ventricular tachycardia

21
Q

What do you look for in interpreting an ECG

A

ARI BAR

Any electrical activity

Rate

Irregualr or regular rythm

Broad QRS complexes

Absent P-waves

Relationship beteen P-waves and QRS complexes

22
Q

Before interpreting an ECG, what should you always observe first

A

The bloody patient

23
Q

Absent p-waves are a sign of what

A

Ventricualr tachycardia

A. fib

24
Q

What phenomeon is characterised by a gradually increasing PR interval

A

Weckenbach phenoneon

(AKA 2nd degree heart block)

25
Q

When p-waves and QRS complexes don’t match up, what is the likley ECG abnormality

A

3rd degree heart block

26
