Answer: - assess the patient
- treat the underlying cause
-pain
-dehydration

What is a dysrhytmia?
an abnormal rhythm of any kind
What are causes of bradycardia?
- hypothermia
- hypothyroidism
- cardiomyopathy
- MI
- Heart block
- drugs
-digoxin
-beta blockers
-anti arrhymic medicine
What is the intervention for a patient who is bradycardic but is not showing signs?
nothing, just keep monitor and assessing
What is the treatment for sinus bradycardia?
- o2
- ivline
- atropine
- transcutanes pacer
- dopamine/epi
Why is atropine given for sinus bradycardia?
- it increases the AV node which speeds up the ventricle contraction
What is the right way to administer atropine?
fast
too slow will cause the reverse effect of it
How is dopamine or epi given for a patient with SB?
in a continous pump
What can be the cause of sinus tachycardia?
- infections
- fever
- hypoxia
- shock

-dehydration
What is sinus arrhytmia?
SA node is firing in a irregular rate
SA arrhytmias are mostly related to what two things?
- respiratory cycles
- intrathoracic pressure changes
What are the characteristics that makes sinus arrhytmia different with sinus rhythm?
- the p waves and QRS are irregular
- the rate of p and qrs increase during inspiration and decreases during expiration
What type of medication can cause sinus arrhytmia?
digitalis and morphine
What is the sinus pause or sinus arrest?
- when the SA have a misfire
What is the key identifier for PAC?
the p waves
How to treat PAC?
- if they are unfrequent may not need treatment
- correct electrolyte imbalances
- decrease the consumption of alcohol or caffeeine
What differs controlled and uncontrolled a-fib?
uncontrolled the ventricular rate is greater than 100 and controlled is less than 100
Saw tooth appearance is known for?
atrial flutter
What are the first line drug for patient with uncontrolled a-fib?
- calclium channel blocker
- beta blocker
- digoxin
What is the treatment for a-fib?
- drugs
-calcium channel blocker
-beta blockers
-digoxin. - cardioversion if medicines does not work
What is the difference between controlled and uncontrolled afib?
controlled is less then 100 and its uncontrolled if its greater than 100
T or F: Ventricular rate during a fib is regular
False, its irregular
What is the treatment for controlled afib?
anticoagulants
What is the treatment for uncontrolled afib?
beta blockers
digoxin
calcium channel blockers
What is the treatment for a uncontrolled and unstable afib patient?
go immediately with cardioversion
What are the characteristics of junctional rhythm?
p wave might not be present and if its present it should be less than 0.12
-QRS is normal
What is an accelerated junctional rhythm?
the same as juntional rhythm but the rate is between 60-100 bpm
What is the difference between accelerated junctional rhythm and junctional tachycardia?
in junctional tachycardia the ventricular rate is between 100-150
What are the treatment for a stable junctional tachycardia?
- oxygen
- IV access
- vagal maneuvers
- adenosine
- beta blocker
- calcium channel blocker
What is the most common type of SVT?
PSVT
What is the cause of PSVT?
a short circuit in the heart electrical system
