Acute pulmonary embolism (PE) is one of the most serious form of venous thromboembolism. The clinical presentation of PE is variable and often nonspecific making the diagnosis challenging.
✅ Sinus tachycardia (most common).
✅ S1Q3T3 pattern (may be present up to 30% of cases).
✅ Simultaneous T wave inversions in the inferior leads and right precordial leads can be seen.
✅ Right axis deviation.
✅ RBBB (complete or incomplete).
