EKG Flashcards
Reciprocal change
Changes in the opposite leads of ischemic damage; they will mirror what is seen in the damaged tissue
2nd degree AV block
Include ratios
Mobitz type I: Progressive lengthening of the PR interval until there is a dropped beat
“High degree block”- Multiple dropped beats
Atrial bigeminy
Every of the beat is a PAC
Sinus tachycardia vs. PSVT
Sinus tachy = 100-150bpm
SVT= >150bpm
Multifocal atrial tachycardia
Atrial rhythm with irregular, changing p waves due to their differing foci
Junctional rhythm
Slower rhythm that originates in the ventricles, sometimes tachycardic
-Difference between this and A-fib is that A-fib will have changing PR intervals
A flutter
Make sure to count the ratios
A-fib w/ rapid, slow, or controlled ventricular response
Just know thats how to say it
Interpolated PVC
PVC that occurs between two regular beats without having the compensatory pause
> 3PVCs in a row
V tach
Rule of 35 + 12
- > 35 years old
- Deepest S wave in V1 or V2 and add to tallest R wave in V5 or V6
OR
R wave in avL >12
- Strain pattern
- If these criteria are met, the patient has LVH
P mitrale
Notched p wave that makes it look like a lowercase m
-Also called “Left atrial enlargment”
P pulmonale
Peaked P-wave
Also called “Right atrial enlargement”
ST elevations in all leads
Pericarditis
Early repolarization
Can look like ST elevation but if there is normal R wave progression, you know this is benign
Seen in young runners
