EKG Final Flashcards
The most striking feature of this electrolyte imbalance is the peaked T waves it creates; the P wave may also be flattened down
hyperkalemia
This electrolyte imbalance presents with a U wave
Hypokalemia
A shortened QT interval is what kind of electrolyte imbalance?
hypercalcemia
This electrolyte imbalance is known to create a prolonged QT interval
hypocalcemia
a large S wave in lead I, ST depression in II and large Q wave in III with T wave inversion is characteristic of what finding?
pulmonary embolism
True or False: Q wave formation does occur in pericarditis
false
This can cause ST segment elevation and T wave flattening or inversion
pericarditis
What leads do you look for LBBB in?
V5 and V6
What leads do you look for RBBB in?
V1 and V2
this syndrome is classified as having a downward slope in V1 and V2 +RBBB +ST elevation
Brugada syndrome
What is the difference between an old MI and a new MI if they both have Q waves?
ST elevation=new
Q waves without elevation= old
What are the anterior leads?
V1-V4
What artery corresponds with the anterior leads?
LAD
What are the lateral leads?
AvL, I
What artery corresponds with the lateral leads?
left circumflex
What are the inferior leads?
II, III, AVF
What artery corresponds with the inferior leads?
mostly RCA
What are the posterior leads?
V1, V2
What artery corresponds with the posterior leads?
RCA
in ventricular hypertrophy, the axis gets placed toward or away from the hypertrophy?
toward
In an infarct, the axis gets displaced toward or away from the infarct?
away
What axis do you look at to determine deviation?
lead I and AvF
Downward QRS in both lead I and AVF are indicative of what?
extreme RAD
an up-going QRS in lead I and a down going QRS in AVF is called what?
LAD
