Flashcards in Week 3 EKG Lead Placement Deck (31):
1

what does an EKG do?

provides info about electrical system of the heart from 12 different views using 10 electrodes

2

what node is responsible for the automatic beating of the heart

SA node

3

what are indication for EKG? 4

diagnose abnormal conduction, arrythmias, pre-op assesments, abnormalities resulting from genetic factors

4

what are some contraindications to performing an EKG? 2

severe trauma to chest, uncooperative patient

5

what are the complications to doing and EKG?

none

6

to what extent should a patient be clothed for an EKG?

removed clothing from waste up

7

what is the standard patient position?

supine(face up on back)

8

what is the max angle the head can be for EKG

45 deg

9

what happens if a patient cannot lie flat w/ head under 45 deg?

document altered EKG position (this can impact tracing)

10

what step must you do before placing leads and after positioning the patient?

skin prep (gives best electrical conduction)

11

what is involved in skin prep?

de-fat skin with alcohol wipe and then abrade skin with gauze pad

12

if skin is oily what do you do before alcohol and gauze?

wash with soap

13

what if the chest is hairy?q

separate hair or clip them

14

if skin is diaphoretic (sweaty) what steps do you do before alcohol wipe and gauze pad to clean it?

rub with gauze pad to dry

15

to place chest electrodes you will have to ____ and use ___

palpate and use landmarks

16

what if electrodes cannot be placed accurately?

clearly document the actual location of the electrode

17

where does electrode V1 go?

4th intercostal space, right sternal border

18

V2?

4th ICS, left sternal border

19

V3?

equadistant between V2 and V4

20

V4?

5th ICS at midclavicular line

21

V5?

horizontal to V4 at the anterior axillary line

22

V6?

horizontal to V4 at the midaxillary line

23

limb electrodes should be placed...

on fleshy areas of wrists and ankles avoiding bony prominence, on the same spot on each limb

24

what are the three main problems in a EKG?

electrical interference, wandering baseline, muscle tremor

25

how do you troubleshoot electrical interference?

alter electrical activity of the room

26

what is a wandering baseline?

wave form moves up and down over course of tracing

27

what casues wandering baseline?

poor lead connection

28

what does a muscle tremor look like on an EKG?

lines close together and spiking. not as long as the electical interference

29

how do you fix muscle tremors?

quiet the movements of the patient

30

before removing electrodes what do you do?

take recording to physician

31

electrode vs lead

electrode: sticky part
lead: alligator clips
