Atrial Flashcards
sinus brady is decribed as having everything normal except
the rate which is 40-60
what kind of damage can we suspect from a sinus brady
inferior MI
what is the treatment of choice for sinus brady
atropine is an anticholinergic
Sinus tachy is described as having everything normal except..
rate which would be 100-180
In order for something to be sinus tachy you must have a ___wave
P wave
sinus tachy can described as a _______response
compensatory
sinus tachy can be caused by*****
excitement, stress, fever, hypervolemia, hypoxia and pain
How would we treat sinus tachy?
WE NEED TO TREAT THE CAUSE NOT THE RATE
supraventricular contraction have what distinct characteristics?
no P wave no pr
very fast like 150
how would we treat SVT or atrial tachy?
treat the rate—–
if hemodynamically unstable cardiovert
If a patient in SVT or atrial tachy is stable how will we treat?
we will treat by vagal maneuver
Adenosine 6 -12- 12
Ca beta-Dig
What is the main characteristic in A -Flutter
saw tooth waves
fast rate
**Atrial Flutter results in
reduced cardiac output”reduced cardiac kick”
why is a fib or flutter so DANGEROUS
you have blood churing on the walls thus causing clots that can get stuck in lungs causing a PE or in brain causing a Embolic stroke.
what are ways we can treat a flutter
If stable we will first try to control the venticular rate with meds
Ca blocker, beta, Dig or Adenosine
we will then try to overdrive pace
what is the difference between embolic and hemmoragic stroke?
embolic you will feel no pain
hemmoragic you will feel HA and pain due to ICP
Mr. Hill qusetion -what are the two main things we are worried about in a flutter
Ventricular rapis response and A flutter
If a patient has had symptoms of a fib for less than 48 hours we will want to
cardiovert and give amiodarone
If a patient has been in a flutter for more than 48 hours we will first
want to treat with anticoagulants
what is the main characteristics of First Degreen AV block
prolonged PR–benign
First Degree AV Blcok can be caused by
Dig, Beta, Amio
hyperkalemia
SEcond degree type 2
pr progressivly lengthens until qrs is dropped
this is usually benign
can be caused by inferior wall MI
Second degree-Type 2
Mad woman
PR can be normal or prolonged-folowed by a dropped rate
Second Degree -Type 2 is related to insufficiency in the
anterior wall
