20
Q

What does the P wave represent?

A

Atrial depolarisation

21
Q

What does the QRS complex represent?

A

Ventricular depolarisation

22
Q

What does the T wave represent?

A

Ventricular repolarisation

23
Q

What does PR interval mean?

A

Time it takes for electric signal to travel from your atria to ventricles

24
Q

What does QRS interval mean?

A

Time it takes for Ventricular depolarisation

25
Q

What does QT interval mean?

A

Time it takes for Ventricular depolarisation and Ventricular repolarisation

26
Q

What is QTc

A

Correct QT interval

27
Q

How is QTc calculated?

A

QT/ square root of R-R interval

28
Q

What are the normal values for PR interval

A

120-200 ms

29
Q

What are the normal values for QRS interval

A

80-120ms

30
Q

What are the normal values for QT interval

A

360-440ms

31
Q

What is the equation for heart rate from an ECG

A

300/ Number of large squares between R-R

32
Q

What is sinus arythmia

A

Normal irregular rhythm of the heart

33
Q

What happens to ECG during inspiration

A

R-R interval shortens

34
Q

What happens to ECG during expiration

A

R-R interval lengthens

35
Q

What is the mechanism for the change in ECG during inspiration

A

Inspire = vagal tone decreases
Vagal tone keeps your heart rate at a low rate
heart rate increases when you breathe in

36
Q

What is normal in an ECG for athletes?

A

LVH- left ventricular hypertrophy
Sinus bradycardia
1st heart degree block
Sometimes ST elevation

37
Q

What is normal in Caribbean and African populations ECG

A

Inverted T wave in V3
ST elevation
LVH

38
Q

What is a sign of ventricular hypertrophy

A

Big QRS complex
