|
If a patient was symptomatic and had bradycardia, what drug would we administer?
|
atropine
|
|
|
What are the three treatments for sinus arrest?
|
Pacemaker, atropine, and isoproterenol
|
|
|
When looking at an EKG, what is the difference noted between wandering atrial pacemaker and multifocal atrial tachycardia?
|
Wandering atrial pacemaker has rate of < 100.
MAT rate is > 100 |
|
|
What is the treatment for wandering atrial pacemaker?
|
None, unless dig toxicity.
|
|
|
MAT is very common in what very common respiratory disease state? What are some pharmacologic causes?
|
COPD.
Drugs- CCB's, BB's, and amiodarone. |
|
|
What are some relatively normal activities that can cause a PAT? What is the point of the compensatory pause?
|
Alcohol use, tobacco use, caffeine, and stress.
Point of pause is so atria can reset itself. |
|
|
What is the rate for atrial tachycardia/PAT? What are the possible therapies?
|
150-250bpm
Use valsalva maneuver, CCB, vagal maneuver, or oxygen. |
|
|
What is the drug of choice for PSVT?
|
Adenosine
|
|
|
When a patient has atrial flutter, what is the deciding factor as to if they get cardioversion/"paddle whack" or a CCB?
|
Get CCB if assymptomatic; thus get paddle whack if symptomatic
|
|
|
If a patient is comes to the ER with atrial fibrillation, what will we do for them?
|
Cardiovert, coumadin (takes 5 days to work), heparin
|
|
|
When looking at an EKG, how can you tell the difference between a PAT and a premature AV junctional contraction?
|
There is no P wave in the PJC or it is after the QRS and/or inverted.
|
|
|
What would you name a rhythm that had a rate of 20-40 bpm and you would treat w/ atropine?
|
ventricular escape beats/Idioventricular Rhythm
|
|
|
When you have PVC's that alternate with regular heart beats what pattern of PVC's is that labelled?
|
Bigeminy
|
|
|
Three of more PVC's =...
|
V-Tach
|
|
|
What is the treatment for iodiventricular rhythm?
|
atropine and/or transcutaneous pacing
|
|
|
What are two names for 2nd degree Type I AV Block?
|
Type I (Wenckebach, Mobitz Type I)
|
|
|
What are two names for 2nd degree Type II AV Block?
|
Type II (Mobitz Type II)
|
|
|
What is the difference between 2nd degree AV block Type I and type II?
|
Type I:Wenckebach, Mobitz Type I. These rhythms have a steadily lengthing PR interval followed the dropping of the QRS complex.
2nd Degree Type II has a steady PR interval |
|
|
What is the treatment of 3rd degree AV block (atrial and ventricles beat indepently of eachother?
|
pacemaker
|
|
|
What is one of the primary causes of sinus arrhythmia?
|
breathing
|
