PULMONARY THROMBOEMBOLISM
Pulmonary embolism is the blockage of the blood vessels in the lungs usually due to blood clots from the veins, especially the veins in the legs and pelvis.
Dyspnea, chest pain, syncope or tachypnea (respiratory rate of ≥20/min) occur in most cases of pulmonary embolism.
Pleuritic chest pain with or without dyspnea is one of the most frequent presentations of this disease.
Syncope or shock are the hallmark signs of central pulmonary embolism and usually result in severe hemodynamic repercussions.
Signs of hemodynamic compromise and reduced heart flow are also usually present.

Differential Diagnosis

  • Cardiogenic shock, cardiac tamponade, acute valvular dysfunction, aortic dissection, pneumonia, massive myocardial infarction (MI)
