ECG rhythm interp

P53 interpretation of ECG basic

RhythmRate / RegularityP waveP wave durationQRS durationRation P to QRS notes
ECG Rules and Characteristics (5 step)Rhythm Interpretation Analyze Rate (How fast or slow) Analyze Rhythm (Regular?) (occasional irreg)(reg irreg)(irreg irreg) Analyze P wave (P present)(P regular to Ps)(One P for each QrS)(upright or inv)(look alike) Analyze PRI (norm 0.12-0.20sec) Analyze QRS (look alike)(Duration norm 0.04-0.12)
Normal Sinus Rhythm (NSR) 60-100bpm / Reg-Reg Upright and similar 0.12-0.20sec & consistent 0.04-0.10sec 1P:1qRs
Sinus Tachycardia >100bpm / Reg-Reg Upright and similar 0.12-0.20 sec & consistent 0.04-0.10 sec 1P:1qRs
Sinus Bradycardia <60bpm / Reg-Reg Upright & similar 0.12-0.20 sec & consistent 0.04-0.10 sec 1P:1qRs
Premature Atrial Contraction(PAC) usually <100bpm /dependant on underlying rhythm / Irregular Early & upright/ different from Sinus 0.12-0.20sec / different from Sinus 0.04-0.10sec 1P:1qRs
Atrial Flutter Atrial: 250-350 / Ventricle: 150 common/ A: Regular Vent: Reg or Irregular Not identifiable / F waves uniform (sawtooth) not measurable 0.04-0.10sec n/a due to no P defined
Atrial Fibrillation Atr: 400-700 /Vent: 160-180 /A: Irr V: Irr not identifiable P / f waves may be seen unable to measure usually normal n/a due to no P
Paroxysmal Atrial Tachycardia(PAT) usually 160-220bpm / Reg-Reg differ in shape from Sinus/ difficult to identify due to rate Normal when P identified / short if WPW normal 1P:1qRs onset sudden often inititated by PAC
Premature Junctional Conatraction(PJC) usually <100bpm (dependant on undr) /Irregular Inverted before or after qRs or not visible <0.12sec when inverted P is before qRs 0.04-0.10 sec 1P:1qRs if P visible
Junctional Escape Rhythm 40-60bpm or 61-100 (accelerated)/Regular Inverted before or after qRs or not visible <0.12sec when inverted before QRs 0.04-0.10sec 1P:1qRs if P visible
Junctional Tachycardia 101-200bpm/Regular Inverted before or after qRs or not visible <0.12sec when inverted before QRs 0.04-0.10sec 1P:1qRs if P visible
Supraventricular Tachycardia (SVT)/ umbrella term used when unable to distinquish which rhythm present >150bpm / absolutely regular P wave not visible not measurable 0.04-0.10sec
Premature Ventricular Complex (PVC) dependant / A: Reg V: Irr usually absent if present not associated with PVC if present? 0.12 or greater / bizarre and notched n/a ST&T often opposite qRs/ every other bigeminy / multifocal if different shape/ RonT =PVC
Ventricular Tachycardia (Vtach) >100bpm usually not >220 / usually regular no P or not associated n/a Wide and bizarre three PVC in row or more at 100bpm is Vtach
Ventricular Fibrillation (Vfib) could be any no regularity/chaotic undulating no P n/a No qRs
Idioventricular Rhythm 20-40bpm / 40-100bpm(accelerated) / Regular No P associated with qRs n/a >0.12sec notched /bizarre ST/T oppposite direction of qRs
Aystole 0 / unless P present then could be reg or irregular may be present n/a not there not there
1st degree AV block 1P:1qRs indicated by prolonged PRI (>0.20sec but not >0.40sec)
2nd degree AV block type 1 Ap not equal V More P waves than qRs PRI progressively increases until P appears w/o qRs cyclic pattern reoccurs non-conducted Pwave
2nd degree AV block type 2 could be Reg or Irreg More P waves than qRs PRI consistent qRs normal (if wide Bundled Branch block) non-conducted P waves present
3rd degree AV block More P waves than qRs P not related to qRs (P too close or too far) PRI varies greatly qRs normal or wide could have regular Vent

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.
