30
Q

Posterior where are reciprocal changes

A

V1-V4

31
Q

1st degree heart block rule

A

R far from P 1st degree

32
Q

2nd degree type 2 characteristics

A

longer, longer, drop

33
Q

2nd degree type 2 characteristics

A

some P’s don’t Get through

34
Q

3rd degree heart block characteristics

A

P’s and Q’s don’t agree

35
Q

one large square time

A

0.2s

36
Q

one small square Tim,e

A

0.04

37
Q

rule of 300 to calculate HR

A

300/ R-R int (in large squares)

38
Q

name the rates of rule of 300

A

1=300
2=150
3=100
4=75
5=60

39
Q

how to calculate rate using rhythm strip

A

HR= no. of QRS x 6

40
Q

define an ecg’s rhythm,

A

it is where the action potential started

41
Q

define a sinus rhythm

A
  1. P wave upright in II
  2. P waver inverted in AVR
  3. each P looks the same (within the same lead)
42
Q

what is cardiac axis

A

average direction of electrical potential during dfepolirasation of the ventricles

43
Q

what do you look at to determine axis

A

if the QRS is mostly up (positive) our down (neg) in lead I and AVL

44
Q

cherectertics of normal axis

A

I: positive
AVL: postive

45
Q

LAD cherecteritisics

A

I: positive
AVL: neg

46
Q

rad charectereisitics

A

I: neg
AVL: pos

47
Q

Extreme axis cherecterisitics

A

I: neg
AVL: neg

48
Q

what is the PR interval

A

atrial depolarisation and contraction

49
Q

normal duration of PR

A

0.12-0.2 (3-5 box)

50
Q

trick to finding PR

A

if you find one that begins close to the beginning of a big box, and QRS begins before the end of that box, you know it is not prolonged

51
Q

what is the QRS representing

A

ventricular depolarisation

52
Q

QRS should be…

A

less than 3 small boxes

53
Q

a wide QRS represents

A

abnormal ventricular condition, which will affect the shape of the ST segment and T waves

54
Q

what is the Q wave

A

the first deflection of the QRS if it is downwards

55
Q

what dose the Q wave represent

A

normal L to R depolirsation of the septum

56
Q

where is the Q wave normally seen

A

in L sided leads: I, AVL, V5-V6

57
Q

how long should Q wave be

A

small box

58
Q

big Q most often due to

A

pervious MI

59
Q

R wave progression in V1 should be

A

negative

60
Q

R wave progression in V6 should be

A

positive

61
Q

in V what is the relationship between QRS and ST segment

A

QRS should be larger than ST

62
Q

what dose the ST segment represent

A

nop eléctricas activity, thus should be flat

63
Q

T wave usually inverted in…

A

V1, AVR

64
Q

Qt is measured from

A

Start of the QRS to end of the T

65
Q

general rule for QT int

A

QT should be less than half the preceding R-R int

66
Q

normal QT form men

A

less than 440ms

67
Q

normal QT for women

A

less than 460mms
