  4. QRS normale Durata: 0.06"-0.10" Q non superiore a 0.04" in D'1, D2, aVL, aVF Q puo' essere > 0.04" in D3, aVR, V1, V2 Q in D1 e D2: non > 2 mm, non > 25% di R In precordiali: voltaggio R sale da V1 a V5 voltaggio R in V6 > a Q o S V3, V4: zona transizione (complessi isodifasici) tra ventr dx (V1, V2) e ventr sin (V5, V6) V1-V2: intervallo tra inizio QRS ed apice R (R')< 0.03" V5-V6: intervallo tra inizio QRS ed apice R (R')< 0.05"

  5. Asse elettrico e’ risultato di vettori che generano QRS

  6. Question 2 of 10 What is the QRS duration seen here? A. 0.04 sec B. 0.06 sec C. 0.10 sec D. 0.12 sec E. 0.14

  7. What potentially fatal abnormality can be seen in this ECG? A. Increased PR interval B. Poor R wave progression (V1 - V3) C. Increased QT interval D. Decreased QT interval E. Increased P wave amplitude

  8. Determine the QRS axis for this ECG:A. IndeterminateB. +90 degreesC. -30 degreesD. -45 degreesE. +150 degrees D1 neg aVF pos D2 isodif

  9. Determine the QRS axis for this ECG:A. IndeterminateB. +90 degreesC. -30 degreesD. -45 degreesE. +150 degrees

  10. Determine the axis for this ECG:A. +90 degreesB. IndeterminateC. +30 degreesD. -30 degreesE. -150 degrees D1 pos aVF pos D3 isodif

  11. Determine the QRS axis for this ECG:A. -60 degreesB. -45 degreesC. +60 degrees D. IndeterminateE. 0 degrees D1 pos aVF isodif

  12. aVF neg Determine the QRS axis for this ECG:A. -75 degreesB. -30 degreesC. 0 degreesD. +45 degreesE. Indeterminate D3 neg D2 neg aVR pos D1 pos

  13. Determine the QRS axis for this ECG:A. -15 degreesB. +15 degreesC. +60 degreesD. +105 degreesE. Indeterminate axis Occasionally each of the 6 frontal plane leads is small and/or isoelectric. The axis cannot be determined and is called indeterminate. This is a normal variant

  14. Determine the QRS axis for this ECG:A. -100 degreesB. -30 degreesC. +15 degreesD. +90 degreesE. Indeterminate aVF pos D1 isodif
