Because the heart’s electrical system is complicated, diagnosing abnormal heart rhythm (arrhythmias) can be difficult and requires heart rhythm experts who use special testing equipment. To find the problem, a doctor will take a medical history, ask about symptoms, give a thorough physical exam, and order specific tests.
This test searches for reasons for Fainting, or temporary passing out (syncope). Heart rhythm and blood pressure are carefully monitored while the patient rests on a special table. The table tilts the patient upright at a 70-80 degree angle for 30-45 minutes. If the patient faints, it usually means that he or she has a condition called vasovagal or neurocardiogenic Fainting, which is not life threatening.
