Transcript

  • 1. ACUTE PERICARDITIS ECG
  • 2. Pericardium to pericarditis
  • 3. INCIDENCE • 90% of patients with acute pericarditis have ECG changes
  • 4. Four stages< 50% of patients • I • II • III • IV
  • 5. Stage I • Sinus tachycardia is common • ST-segment elevation in all leads except aVR and V1 • Normal T-wave axis • PR-segment depression • ST segment is usually concave upward • No regional lead distributions
  • 6. 12 Lead ECG in stage I
  • 7. All the leads except
  • 8. Except V1 and aVR
  • 9. Stage II • ST segment returns to baseline and flattening of T waves occurs, typically during several days
  • 10. Stage III • T-wave inversion occurs in stage III when ST segment is normal • Sometimes with ST-segment depression
  • 11. Stage IV • ST segments and T waves return to normal • Complete normalization may require weeks to months
  • 12. Variation • Classical changes may not go through each of these phases in an individual case • PR-segment depression has been reported in about 80% of patients • PR-segment depression is one of the earliest electrocardiographic • Manifestations of pericarditis, occurring in the first few hours of presentation and often preceding ST-segment elevation • Ventricular tachycardia and conduction abnormalities are suggestive of myocardial involvement with ischemia(Myopericarditis)
  • 13. Differential diagnosis • Early repolarisation • Acute STEMI
  • 14. Normal variant of early repolarisation The ST-segment elevation of pericarditis can be differentiated from the normal variant of early repolarization if the ratio of ST to T wave in V6 is greater than 25%
  • 15. Acute STEMI • ST elevation goes hand in hand with T wave inversion
  • 16. With love
