27
Q

the cardiac axis 11 -5 oclock

which three leads easily show normal axis

should they be pos or neg

which one should be more pos if axis is normal

A

1 2 3

positive

lead 2

28
Q

left axis diviation

A
29
Q

what does right axis divation look like

in what leads

A
30
Q

a right axis diviation may indicate what

A

pulmonary embolus

copd

mi

RVH

left posterior fascicular block

31
Q

a left axis diviation may indicate what

A

conduction defect

LBBB

paced rhythm

WPW

LVH

Left anterior fascicular block

32
Q

why is the r wave transition point important

A

if the ventricle right is in larged the transition will move from its normal v4 v5

v5 v6 this characteristic of chronic lung disease

33
Q

left axis div LVH

LAD

A

left ventricle hyperotrophy

left axis diviation

34
Q

Right axis devation

RAD

RVH

A

right ventricle hypertrophy

35
Q

horizontal left div some reasons for LAD

A

mi in the right side

obestity

pregnant

acites

lbbb

lafb

36
Q

vertical right div

A

some reason for rad

mi old or acute

tall thin

emphysema

pulmonary disease

37
Q

isoelectric

what is it

A

neutral equal positive negative

38
Q

isoelectric find on ecg then use the 90 degree then pos

A

find on ecg

fine tune

neg ant clockwise

pos clockwise

39
Q

lead placement

A
40
Q

the ecg will do most of the work but remember

A

electrodes to correct limbs

ensure good electrical contract

calibration and speed 25 mm/s 1Mv high two squares 1cm

patient comfortable and relax

41
Q

how to report an ECG

A

rhythm regular or not

conduction intervals PR interval 0.12-0.20s QRS 0.08-0.10s

cardiac axis

description of QRS complexes

description of ST segment and T wave s

42
Q

one P wave per QRS complex 0.12-0.20s 3-5small squres

normal or not

A

within range

43
Q

one p wave per QRS more the 0.20s 5 small boxes

what is this

A

1 st degree block

may be a sign of

CAD

digoxion toxicity

eletrolyte embalances

rheumatic carditis

44
Q

progressive lengthening of the PR interval

one non conducted P wave

next conducting beat has shorter conducted beat

p wave may be in a distortion of the t wave ( with any other rhythm)

what is this

A

wenckebach /mobitz type1

45
Q

PR interval more than 5 small squares 0.20s

1 P wave is not followed by a QRS

what is this rhythm

A

seconded degree heart block

mobitz type2

46
Q

P wave rate 90/min

no relationship between QRS complexes

QRS complexes rate 36min

abnormally shaped QRS complexes

A

Third degree heart block

47
Q

P wave qrs not linked

RAD

broad QRS complexes

RBBB

A

complete heart block

48
Q

it is impotant to recognize LBBB why

best seen in what lead

A

no further interpretation can be done

V6

w with notch

49
Q

RBBB can mean what about the patient

which lead best to see

RSR

A

could be normal

right side of heart

V1

50
Q

bifascicular block

LAFB

LPFB

A

left antior fascicular block normal QRS but LAD

Left pos fascicular block normal QRS but RAD
