Sudden rapid heartbeat, as with my afib, moves upwards and causes dizziness, shortness of breath, ears ringing and hearing diminished, tingling of face around nose and eyes and scalp and suddenly goes as quick as it came. I know I have afib (for 16 yrs), and these symptoms happen daily of late.. I can be sitting at the computer, walking, or sitting on the couch. If out walking, I can hardly make it back to my truck without the drastic need to sit down.
