Flashcards in 10 minute topic EKG and Dysrhythmias Deck (22):
1

Cardiac dysrhythmia

heartbeat disturbances (beat formation, beat conduction, or myocardial response to beat)

2

EKG use

record the electrical activity of the heart over time

3

Who uses EKG monitoring?

Pts with: bradycardia, heart block, Atrial fibrillation, Supraventricular tachycardia (SVT), Ventricular tachycardia, Ventricular fibrillation

4

Some causes of Dysrhythmias

Electrolyte imbalance can cause dysrhythmias, CKD, COPD, ESLD, Rx or ETOH abuse, shock, hypovolemia, pericarditis

5

Classification of Dysrhythmias

by the side of origin (SA node, atria, AV node, ventricles) & effect of rate and rhythm of the heart (bradycardia, tachycardia, heart block, premature beat, fluttering, fibrillation or asystole)

6

Dysrhythmias in clients post MI

leading cause of death primarily if they had a left ventricular MI

7

bradycardic dysrhythmia

the patient is symptomatic (any rhythm less than 60/min)

8

bradycardic dysrhythmia sx

Light headed
They may faint
They may have syncope

9

bradycardic dysrhythmia tx

atropine
pacemaker

10

dysrhythmias in the elderly

often atypical presentation

11

Atropine

cholinergic antagonist
raises the heart rate
first line tx for bradycardia .

12

Rapid Atrial flutter s/s

Palpitations
SOB
Anxiety
Angina
Syncopal
Presence of HF

13

Afib, SVT, VT with a pulse meds

Commonly use Amniodarone, adenosine, verapamil

14

Afib interventions

Assess for SOB, chest pain, hemoptysis
risk for throwing small clots and having a stroke

15

Afib tx

commonly use anticoagulants
synchronized cardioversion

16

VT with pulse

3 or more PVCs in a row or greater that is considered VT

17

Pulseless VT or Vfib tx

Amiodarone, lidocaine, epinephrine- push quickly and call a code

18

Cardioversion

Elective ts
delivery of a direct countershock to the heart synchronized to the QRS complex

19

Defibrillation

delivery of an unsynchronized, direct countershock to the heart
stops all electrical activity of the heart, allowing the SA node to take over and reestablish a perfusing rhythm

20

Pre procedure interventions for Cardioversion

anticoagulation for 4 to 6 weeks prior to cardioversion therapy to prevent dislodgement of thrombi into the bloodstream
administer O2
Hold digoxin 48 hours prior

21

Intraprocedure interventions for Cardioversion

everyone needs to be clear of the PT to avoid shock
Administer a prescribed antidysrhythmic

22

postprocedure interventions for Cardioversion complications

embolism
CVA
MI
decreased C/O due to damage to heart tissue from procedure
