Clinical Features:

[select name="Alternative" value="No (0 points)=0|Yes (1 point)=1"] <-- Other diagnosis less likely than PE? 
[select name="Rate" value="No (0 points)=0|Yes (1 point)=1"] <-- Heart rate greater than 100 beats per minute?
[select name="Immobilization" value="No (0 points)=0|Yes (1 point)=1"] <-- Immobilization or surgery in the last 4 weeks?
[select name="Previous" value="No (0 points)=0|Yes (1 point)=1"] <-- Previous DVT or PE?
[select name="Hemoptysis" value="No (0 points)=0|Yes (1 point)=1"] <-- Hemoptysis?
