Because of right heart strain, certain changes on electrocardiography may occur in patients with pulmonary embolism, including T-wave inversion on precordial leads, right bundle branch block, and the well-known but uncommon S 1 Q 3 T 3 pattern. 12 Such changes are neither sensitive nor specific for pulmonary embolism.SORT: KEY RECOMMENDATIONS FOR PRACTICE Clinical recommendation Evidence rating References In patients with a low pretest probability of DVT or pulmonary embolism, a negative result from a high-sensitivity d -dimer assay is sufficient to exclude venous thromboembolism.In addition, many patients have concomitant symptoms and signs of DVT.

Diagnosing deep vein thrombosis (DVT) and pulmonary embolism (PE) may be difficult as the signs and symptoms associated with these disorders.Magnetic resonance venography has been studied for DVT diagnosis and appears to have sensitivity and specificity equivalent to that of ultrasonography. 29 Compared with ultrasonography, magnetic resonance venography is more expensive and has not been studied as extensively.D-dimer is used in the diagnosis of deep vein thrombosis among patients with low or unlikely probability of venous thromboembolism.In patients with preexisting dyspnea (caused by heart failure, chronic obstructive pulmonary disease, or another process), worsening of dyspnea may be the only symptom indicative of pulmonary embolism.
