10 minute topic EKG and Dysrhythmias

Question 1

Cardiac dysrhythmia

Answer 1

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

Question 2

EKG use

Answer 2

record the electrical activity of the heart over time

Question 3

Who uses EKG monitoring?

Answer 3

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

Question 4

Some causes of Dysrhythmias

Answer 4

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

Question 5

Classification of Dysrhythmias

Answer 5

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)

Question 6

Dysrhythmias in clients post MI

Answer 6

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

Question 7

bradycardic dysrhythmia

Answer 7

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

Question 8

bradycardic dysrhythmia sx

Answer 8

Light headed
They may faint
They may have syncope

Question 9

bradycardic dysrhythmia tx

Answer 9

atropine

pacemaker

Question 10

dysrhythmias in the elderly

Answer 10

often atypical presentation

Question 11

Atropine

Answer 11

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

Question 12

Rapid Atrial flutter s/s

Answer 12

Palpitations
SOB
Anxiety
Angina
Syncopal
Presence of HF

Question 13

Afib, SVT, VT with a pulse meds

Answer 13

Commonly use Amniodarone, adenosine, verapamil

Question 14

Afib interventions

Answer 14

Assess for SOB, chest pain, hemoptysis

risk for throwing small clots and having a stroke

Question 15

Afib tx

Answer 15

commonly use anticoagulants

synchronized cardioversion

Question 16

VT with pulse

Answer 16

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

Question 17

Pulseless VT or Vfib tx

Answer 17

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

Question 18

Cardioversion

Answer 18

Elective ts

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

Question 19

Defibrillation

Answer 19

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

Question 20

Pre procedure interventions for Cardioversion

Answer 20

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

Question 21

Intraprocedure interventions for Cardioversion

Answer 21

everyone needs to be clear of the PT to avoid shock

Administer a prescribed antidysrhythmic

Question 22

postprocedure interventions for Cardioversion complications

Answer 22

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