20
Q

Application of limb leads 4 shows us what?

A

LEAD II

21
Q

Lead=

A

Wires

22
Q

Electrode=

A

Stickers

23
Q

Monitor paper tells us….

A

Time
Amplitude

24
Q

P wave shows…

A

Atrial Depolarization
- Present and upright

25
Q

QRS Complex indicates…

A

Ventricular Depolariaztion

26
Q

T wave indicates….

A

Ventricular Repolarization

27
Q

SIX SIMPLE EKG INTERPRETATION -STEPS

A
  1. Identify and Examine P wave (straight and upright)
  2. Measure PR interval (0.12-0.20 sec)
  3. Measure QRS Complex (0.06-0.12 sec)
  4. Identify Rhythm ( regular or irregular )
  5. Identify Heart Rate (SIX SECOND STRIPS: count number of R’s in between the 3 lines and multiply by 10!!!)

Big BOX method- 300 divided by the number of big boxes between 2 R’s

  1. Interpret :)
28
Q

4 LEAD PLACEMENT

A

Christmas on the bottom
Black and white on top

White to write (top)
Red to bed (bottom)

29
Q

Limb leads

A

4 leads

Arms and legs

30
Q

Normal Range of the Heart

A

60-100bpm

31
Q

12 lead- why?

A

ST change? for an MI

32
Q

ST elevation is indication of….

A

an MI (STEMI- ST ELEVATION MYOCARDIAL INFARCTION)

33
Q

INTERPRETING a 4 lead- LEAD II

A
  1. Calculate the rate
    - 300 rule (regular) / 6 rule (irregular)
  2. Rhythm
    - regular or irregular?
    - measure R waves
  3. P waves
    - present and upright
    - evidence of the atria contracting
  4. PR interval
    - 0.12-.20 secs (3-5 small boxes)
  5. QRS duration
    - Normal duration 0.08-0.12 (less than 2 small boxes)
    - evidence of ventricular contraction
34
Q

T Wave shows:

A

ventricular repolarization!

35
Q

Normal Sinus Rhythm

A

Rhythm; Regular
Rate: 80 bpm (60-100bpm)
P waves: Upright and regular
PR interval: greater than 5 small boxes? (0.12-0.20)
P wave for every QRS?
QRS: less than 2 small boxes? (0.04-0.12)

36
Q

Sinus Tachycardia

A

Normal but rate= ELEVATED

37
Q

Sinus bradycardia

A

normal but rate= LOW

38
Q

Arterial Fibrillation

A

Rhythm: irregular
Rate; 90bpm
Waves: non discernable
PR interval: none
QRS; 0.08 (norm; 0.04-0.12)

39
Q

Normal PR interval:

A

PR: 0.12- 0.20 secs (3-5 small boxes)

40
Q

Normal QRS interval:

A

QRS: less than 2 small boxes (0.04-0.12)

41
Q

What are the P waves evidence of?

A

Atria contracting
