	History of DVT (0.64)
	History of cardiovasc dx (-0.51)
	History of pulmonary dx (-0.89)
	Acute onset of dyspnea (2.0)

Data action

 

     
 
Include literature references: Yes   No

 

 

Notes

• The Cor pulmonale on EKG term can be checked if there is evidence of S1Q3T3, S1S2S3, negative right chest T waves, right bundle branch block (transient), or pseudoinfarction.

 
Equations used
 

FactorSum = AgeRange + Sex + ClinicalFactors

Risk = 100 / (1 + e(3.43-FactorSum))

 

 

Calculation Details and Variables

• Equation parameters such as Age Range, have two or more discrete values that may be used in the calculation. The numbers in the parentheses, e.g. (0), represent the values that will be used.
