112 EKG refresh Flashcards
Normal Sinus Rhythm
Bigemeny
Tachycardia
Bradycardia
Flutter
Electrical problem
comes from around the pulmonary veins or mitral valve
afib
irregularly irregular
almost always originates from the pulmonary veins and has to be a left sided ablasion.
Done transseptally from the right to the left because you do not want to put a hole in the right atrium. It will not clot however the septum will.
Pt is heprinized. Cases are usually around 4-5 hours.
AV block Type 1
2nd degree heart block
You are only getting every other QRS, you get a P, then another P, then a QRS
3rd degree heart block
You get your P, then QRS, then 2 P’s, then your QRS, then 1 P and QRS.
You miss every other. When you get 2 P’s in between the QRS which is your clue this is a third degree heart block.
Junctional
Multifocal
Meaning it is changing directions
Ventricular Pacing
Pts with ejection fractions of 25% or less qualify for a pacemaker because studies have shown that a dual chamber pacemaker can increase your ejection fraction up to 25%.
Atrial Pacing
This is ST elevation or a Tombstone
Needs a stemi. Our bread and butter :)
ST Elevation with artifact
artial tachycardia with artifact
vtach with artifact and vfib
asystole with artifact
Ventricular standstill on the nursing monitor
Inferior MI on the nursing monitor
Torsade
This can occur cannulating a vessel. This is a shockable rhythm.
idioventricular on the nursing monitor
Sinus rhythm post ischemia on the nursing monitor
LBBB on the nursing monitor
RBBB on the nursing monitor
you really need a 12 lead EKG to see all of the detail of the Blocks
AO and LV normal pressures
The doctor is looking at the bottom of the LV waveform to see the gradient.
When you are doing a dual lumen pigtail, the doctor is looking at the gradient between the AO and the LV at the top.
Normal AO pressure
AO pressure wave corresponds with the EKG haveing PVC’s
Dampping in a patient with aortic stenosis. We have a very tight valve so the pressure above the valve is going to be dampened. It is a wider wave and lower pressure.
There will also be dampping at the with your curve top with sever disease especially at the ostium.
Aortic regurgitation.
It still have the shape of an aortic waveform but the valve is insufficient making it very big.
LV and AO wave showing mitral stenosis.
AO wave with aortic regurgitation
AO wave with MR
Blue line is where we measure LVEDP.
We slow down the wave to get more detail.
