Can Fainting Be A Sign Of A Dangerous Heart Rhythm Problem?

— -- Question: Can fainting be a sign of a dangerous heart rhythm problem?

Answer :Fainting generally means that the brain isn't getting enough blood supply from the heart. This could be something very simple, but it can be the sign of a dangerous heart rhythm problem, either a very fast heartbeat or a very slow heartbeat. A clue to a dangerous cause would be to explain to your doctor whether you experience palpitations just before you have the fainting spell. If you do, further testing is needed.
