Atrial fibrillation symptoms include heart palpitations, shortness ...Read more

Sometimes I feel just slightly out of breath for no reason. Could this be atrial fibrillation?

Possibly.: Possibly. You can check your pulse during these episodes and see if it is irregular, which may be a clue the shortness of breath is coming from some heart arrhythmia. To make the diagnosis officially, some recording of the heart rhythm needs to be made. This can be via 12-lead ekg, 24-hr holter monitor, or 30-day loop monitor. ...Read more

Can an atrial fibrillation be lethal?

Only if…: Only if the atrial rate is conducted in a very rapid fashion to the lower chamber. Your heart has built-in protection to keep this from happening. However, patients with a condition known as wolff parkinson white sometimes lack this protection and under the right circumstances can die as a result of atrial fibrillation. ...Read more
