ECG: Congenital Heart Disease

  1. 1. ECG OF THE WEEK<br />Prof.VIJAYARAGHAVAN‘S UNIT<br />B.Elavazhagan.<br />
  2. 2. A 20 YEAR OLD MALE, A KNOWN CASE OF CHD PRESENTED TO THE opd.<br />
  3. 3. ECG <br />
  4. 4.
  5. 5. ECG<br />
  6. 6. Summary of the findings <br />Rate – 120/min<br />Sinus rhythm<br />Tall peaked P wave in lead 2 <br />Predominantely positive P wave in V1<br />PR interval- 0.16 s,<br />QRS Complex –0.12 s,<br />ST ,T normal;<br />Extreme right axis <br />
  7. 7. Contd……….<br />QRS configuration <br /> – V1 shows RS complex;<br /> abrupt change to rS in V2;<br /> leads V3-V6 shows rS complexes<br />aVR shows qR complex.<br />Lead 1 shows deep S wave <br />Lead 2 & 3 shows S waves<br />
  8. 8. INFERENCE<br />Right ventricular enlargement <br />Right atrial enlargement <br />Right axis deviation<br />S 1 S 2 S 3 pattern <br />
  9. 9. Criteria FOR RVH <br />SOKOLOW LYON CRITERIA :<br /> R V1 + S V5/V6 > 1.1 mv<br />BUTLER LEGGET CRITERIA :<br /> Tallest R /R’ in V1 + deepest S wave in <br /> LEAD 1 /V6 – s wave in V1 > 0.7 mv<br />OTHER FEATURES;<br /> -RIGHT AXIS DEVIATION ,CLOCKWISE ROTATION <br /> -RBBB PATTERN ,R: S > 1 IN V1 ,R /R ‘ > 5 mm <br /> P WAVE AXIS > 60 DEG – ACQUIRED HEART DISEASE <br /> UPTO 60 DEG –CONGENITAL HEART DISEASE <br />
  10. 10. Differential diagnosis for s1 s2 s3 pattern with rvh<br />COPD –P axis > 70 ; low voltage QRS in precordial<br /> leads <br />Endocardial cushion defects –QRS north west axis<br /> LAHB <br /> deep S in lead 2 > lead 3;<br />VSD with PHT –LVH with RVH right axis deviation;<br />Complete TGA – av block and other heart blocks ;<br />
  11. 11. Contd……….<br />Isolated pulmonary stenosis /atresia—<br /> RVH with S1 S2 S3 pattern but deep T<br />wave inversion present in addition<br />Triology of fallot – LAE ,widening of P wave <br />Tetrology of fallot –<br /> - RVH , RAE , S1 S2 S3 PATTERN , right axis<br /> deviation around 120 – 150 degrees <br /> -Rs pattern in V1 abrupt change to rS V2 and <br /> subsequent leads <br /> T inversion may be seen in V1 ,but not in others <br />
  12. 12. diagnosis<br />Since the ecg of our patient has<br />1.RAE<br />2.RVH<br />3.RIGHT AXIS DEVIATION<br />4.S1 S2 S3 PATTERN<br />5.CLOCK WISE ROTATION<br /> THE DIAGNOSIS IS <br /> “TOF”<br />
