EKG Rythms

CARDIO

QuestionAnswer
SINUS - ORRIGINATE in the SA node
examples of sinus rythyms SINUS- Brady rythm arrhythmia tachycardia
Junctional - originates between the SA node- also known as a nodal
junctional exmpales rythym accelerated rhythym tachycardia premature juctional contraction
atrial originate below the SA node
atrial examples fib flutter pre-atrial contraction paroxysmal atrial tachycardia suerventriculare tachycardia
blocks across the AV node first degree block classic 2nd degree block 2:1 wenckebach 3rd degree heart block - complete bundle branch block
ventriculare may originate or occur in the ventricles
ventricular examples tachy fibrillation torsades de pintes premature ventricular contractions
REGULAR SINUS RYTHM 1 p wave for every QRS REGULAR rate - 60-100
sinus bradycardia 1 P wave for QRS REGUALR rate 40-60
sinus tachycardia 1 P wave for QRS regular 100-140
Sinus arrest Rhythm: Regular with sudden pause in rhythm. Rate: 60-100 or < 60/min P waves: Normal with basic rhythm, then absent during pause. P-R interval: Normal with basic rhythm then absent during pause. QRS: normal with basic rhythm then absent during pause.
Premature Ventricular Complex (PVC) P wave and QRS coome early QRS complex is wide
SVT P waves are present but hard to find QRS is norrow 200-300
A fib No discernible P wave irregular 40-140
atrial flutter no P waves has ' F wave instead of sawtoothed regular/irregular verible rate
Vtach no P waves narrow or wide QRS regular >300
V fib no P waves chaotic quivering baseline grossly iregular >300
asystole no P waves or QRS FLATLINE no electircal activity must confirm 2 leads before acting
2nd degree heart block rheumatic heart disease CAD hypotension -ATROPINE External pacing unitil perm can be placed
3rd degreee heart block block across the AV node COMPLETE heart block AV dissociation pacemaker
bi paced biventricular paced — the pacemaker is stimulating both the right and left ventricles wo distinct pacing spikes per beat — one for the right ventricle and one for the left ventricle L & R ventrical block
PEA Oganized ekg rythm but pt is unresponsive wide QRS wave

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.
