WVSOM -- Physio

EKG

QuestionAnswer
Cellular electrophysiologists measure potentials by measuring the inside of the cell with respect to the outside of the cell
Electrocardiographers depend on Surface electrodes
Measurements are recorded as the ________ between two electodes Potential difference
When the depolarizing wave approaches the positive electrode, the deflection is _______ upward
Fully Depolarized All positive inside all negative outside
Repolarization occurs in the _________ direction opposite
The last to depolarize is the __________ to repolarize. first
Sequence of electrical activation and teh ECG Endo -> Epi -> Apex -> Base
Q wave depolariztion of the sepum
P wave depolarization of the atria
S Late lateral depolarization of the left base
ST segment Full depolarization
T repolarization
U Late repolariztion of mid cells in myocardium
QRS Ventrical depolarization
PR segment time between atrial activation and ventricular activation
If conduction is slowed through the AV node, what happens to the PR interval? Lengthens
Bundle Branch Block Wide QRS
cardiac ion channelopathies that can lead to long _____________ QT intervals
Lead I + left arm - right arm
Lead II + Left Leg - Right arm
Lead III + left leg - left arm
aVF + left foot - Head
aVR + right arm
aVL + left arm
Downward deflection of QRS normal in lead aVR
Horizontal plane V1-V6
Interpretation of ECG rate rhythm vector in frontal plane hypertorphy infarction
Rate = (60s/min) / R-R interval
Large box = .2 seconds
1 Large box 300 bpm
2 large box 150 bpm
3 large box 100 bpm
4 large box 75 bpm
5 large box 60 bpm
6 large box 50 bpm
LAD I = upward aVF = Downward
Normal axis I = upward aVF = upward
RAD I = downward aVF = upward
Extreme RAD/LAD I = downward aVF = downward
I 0 degrees
II 60 degrees
III -60 degrees
avF 90 degrees
avL -30 degrees
avR -150 degrees
Quick and easy devation method 1. find isoelectric line 2. find vector that is perpendicular....is it up or down? 3. up is positive vector down is negative vector
Hypertrophy vector movement vector moves toward hypertrophy
infaction vector movement vector moves away infarction

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
