ECG: Quiz ECG: Quiz Presentation Transcript

  • ECG QUIZ DR.B.Gowrishankar MD pg Prof.DR.G.Sundaramurthy’s unit(M7)
  •  
    • WHAT IS THE DIAGNOSIS ?
    • HOW DO YOU ARRIVE AT IT ?
  • Features of multifocal atrial tachycardia -different P wave morphology -narrow complex, irregular tachycardia.
  •  
  • Atrial Flutter with 2:1 AV block -flutter line -QRS rate is half the flutter rate.
  •  
  • Saw tooth waveform (250-350 bpm) Irregular AV conduction -QRS complexes conducted in 3:1 & 4:1 ratio Non-specific intraventricular conduction delay (RsR’ complexes in II,aVF & V6.
  •  
  • Features of this ecg -paroxysms of atrial tachycardia rate of 150 bpm. 3:2 sinoatrial exit block Normal QRS axis.
  •  
  • Ventricular tachycardia, 160 bpm, RAD +100` -wide complexes & AV dissociation -a capture beat -a fusion beat.
  •  
  • Sinus rhythm-monomorphic wide complex tachycardia. AV Dissociation ,independent atrial activity. Features of Inferior wall MI -deep Q waves,ST elevation & T wave inv. In leads III and aVF. -reciprocal ST depression in leads I & aVL.
  •  
  • Sinus rhythm –atrial ectopics. RAD, incomplete RBBB pattern Complete heart block. Acute inferior MI -ST elevation in leads II & III -reciprocal changes in leads I,V4-6. Polymorphic VT -multiple morphologies -varying R-R intervals
  •  
  •  
  •  
  •  
  • Wide complex tachycardia LAD --60` A short R-S interval No AV dissociation.
  • Thank you
