Several: There are several risks associated with atrial fibrillation (af). The first is that af may cause the heart rate to go up which can cause symptoms of dizziness, palpitations and even syncope. Another, more serious risk associated with af is the increased risk of stroke if left untreated. Finally, if the heart rate continues to run high for long periods of time, heart muscle damge can occur.

Feeling bad: The presence of atrial fibrillation increases the overall stroke risk in a patient, however, going into the rhythm is not the time of greatest risk. Any "risk" is thus likely to be related only to the symptoms experienced during the fibrillation.
