As we have been taught in school, treat the patient, not the ECG... however, the ECG can provide clues (as discussed) into the diagnosis. The following is a list of changes seen with patients diagnosed with a Pulmonary Embolism:
- Sinus Tachycardia (73%)
- Prominent S-wave in Lead I (73%)
- "Clockwise rotation" / Late Precordial Transition (56%)
- T-wave inversion in 2 + Precordial leads (50%)
- Incomplete or complete Right Bundle Branch Block (RBBB) (20-68%)
- P-pulmonale (28-33%)
- Right axis deviation (23-30%)
- No significant findings (20-24%)
- S1Q3T3 (12-25%)
- Supraventricular arrhythmias (12%) [21]
