Stepwise interpretation of ECG - #1 ID 380

  1. 1. Stepwise interpretation of ECG ID 380
  2. 2. ID 380 – 53 year old man in the pre-anaesthesia clinic
  3. 3. ID 380 – 53 year old man in the pre-anaesthesia clinic Can you see P waves?
  4. 4. ID 380 – 53 year old man in the pre-anaesthesia clinic Yes: The P waves originate from the sinus node– The rhythm is regular – Each P is followed by a QRS - The PR interval is normal – The rate is 60/min NORMAL SINUS RHYTHM, 60/min
  5. 5. ID 380 - NORMAL SINUS RHYTHM, 60/min There are no signs of left atrial enlargement or right atrial enlargement
  6. 6. ID 380 - NORMAL SINUS RHYTHM, 60/min Let’s now look at the QRS complexes: There is normal QRS axis (between 0 and 90 degrees)
  7. 7. ID 380 - NORMAL SINUS RHYTHM, 60/min The QRS duration is normal : There is no right bundle branch block, left bundle branch block or non-specific block
  8. 8. ID 380 - NORMAL SINUS RHYTHM, 60/min There is no right ventricular hypertrophy or left ventricular hypertrophy
  9. 9. ID 380 - NORMAL SINUS RHYTHM, 60/min There are no QRS signs of myocardial infarction – There are normal ST segment and normal T waves
  10. 10. ID 380 - Final diagnosis: NORMAL SINUS RHYTHM, 60/min NORMAL ECG
