Atrial Complexes and Rhythms
Terms in this set (27)
premature atrial complex (PAC)
NSR and then a complex falls early and is interrupted
PAC is not an entire rhythm- it is a ____ ____
pointy and peaked
if it is a PAC the p wave will look how?
PACs are big in the ____ population
1. rate >150
2. regular rhythm
3. narrow QRS
what are the three defining pieces of SVT?
1. atrial tachycardia
2. sinus tachycardia
3. junctional tachycardia
4. atrial flutter
what are the four possible rhythms that can actually be SVT?
means starts and ends suddenly
when you can identify the rhythm that preceded and you see the onset and cessation of an SVT
perfusion (decreased BP)
what are you worried about when you see a run of SVT?
(stimulates the vegas nerve to decrease HR)
what is the intervention for a patient who is asymptomatic with a stable SVT?
adenosine 6mg IVP over 1-3 sec (physician push)
what is the intervention for a patient who is symptomatic with SVT
what is the half-life of adenosine?
brief asystole (flushed, diaphoretic, perfuse vomiting)
what usually happens when you administer adenosine?
what is the treatment for an unstable SVT?
what does synchronized cardio-version cause?= _____ _____
synchronized cardioversion is the delivery of electricity to the ___ wave of the qRS complex, avoiding delivering energy on the vulnerable ___wave
when the AV Node usually blocks some impulses and the atrial rate > ventricular rate
no p waves, and a saw-toothed appearance, (can be regular or irregular)
control the ventricular rate
(Ca channel blockers, beta blockers)
what is the goal for stable treatment of Atrial flutter
what is the treatment for unstable atrial flutter?
> 48 hours
when do you give anticoagulation during atrial flutter?
when the atria does not uniformly depolarize (no defined P wave), blood polls in the atria and it quivers, loss of atrial contraction/kick
what is the rhythm in atrial fibrillation?
name the rhythm: irregular R-R, no definable P waves, narrow qRs
control the rate (Ca channel blockers and beta blockers, dig, amioderone)
what is the intervention for asymptotic (stable) a fib?
what is the HR for a fib with RVR?
what is the treatment for unstable a fib?
