PULMONARY EMBOLISM-ECG

1. The only specific (but not sensitive) ECG changes seen with PE are tachycardia and right ventricle strain from acute cor pulmonale.

2. On ECG, right heart strain = SIQ3T3; that is, the S wave is large in I, the Q wave is large in III, and the T wave is inverted in III.

3. ECG also helps rule out MI.
