Physical examination will try to look for signs that will give direction to the potential diagnosis. Heart monitoring may be done to look for heart rhythm disturbances. Blood pressure may be checked both lying and standing to uncover orthostatic. Examination of the heart, lung, and neurologic system may uncover a potential cause if these are abnormal. Initial diagnostic tests may include an ( ) and screening blood tests like a ( ), glucose, and kidney function tests. blood tests may be performed.

Abnormal heart rhythms and rates may be uncovered as the potential cause of syncope. A can be used to uncover orthostatic and is usually done on an outpatient basis. The patient is placed at an angle on a table for 30-45 minutes (every institution has its own protocol) and blood pressure and pulse rate are measured with the patient in different positions.

(CT scan) or magnetic resonance imaging ( ). Often these tests are normal and a presumptive diagnosis is made of a non life-threatening event.
