For years I had from time to time the feeling of low blood sugar. I would eat something and the feeling would go away. I thought it was no big deal and the symptoms occurred several times a year but I had no further symptoms. Then one day I had palpations that did not go away for about 6 hours. We were out of town and when we came home, we called our doctor and he sent me to the emergency room. By the time we got there the symptoms had subsided and I was sent home. About 2 years later, I had another long episode of the flutter and this time arrived at the Emergency Room is plenty of time for them to document what was happening. That led to ultimately getting ablation to my heart... fascinating to watch on the monitor as the doctor guided the camera and something to cauterize the misbehaving electrical element in my heart. The thing that now concerns me is all the people who have atrial flutter and do not know it but assume that the feeling of low blood sugar was just that as they go on with the day. For me the symptoms have been a part of my life for 40 years and I suppose at any time there could have been serious complications, including death. So I am telling anyone who will listen what it felt like and to pay attention to it. PS... the procedure was long but painless and very interesting.

I have had type 2 diabetes for several years controlled by tablets. Recently I felt dizzy after walking quickly, was out of breath, but did not actually faint. I had three similar attacks always after walking quickly (I have a stenosis in my right leg). I was diagnosed with an irregular heart beat and rapid pulse, admitted to a cardiac ward for treatment and am now currently taking warfarin. My condition is being closely monitored by the hospital.

My first symptom of atrial flutter occurred while playing soccer. Winded, short of breath as if out of shape, overexertion. Then noticed my heartbeat going crazy. I laid down and began to break into cold sweat. Experienced pressure and pain in chest, upper back, and neck. Light headed. After 30 min, the symptoms didn't stop, and I went to the ER. I was hooked to a heart monitor--230 BPM. Administered IV Adenosine 3X. That didn't work. Then administered another medication, which finally worked after 5 minutes. The doctors could not figure out the cause. I think it was from taking Diprovan with Adderall (this issue was serious side effect). I had been taking Adderall for three years with no issues. Diprovan was the only thing new (five days into it flutter occurred).

I am 54 years old, have had atrial flutter for 20 years. My cardiologist says it's from an ASD repair, (hole in my heart) repaired at age 10. It triggers from the area that I had surgery. I guess it's common for this to appear years later. I agree it is very frightening when it happens, and I'm considering ablation procedure, which they claim is very successful. It seems to happen when I'm tired, stressed, or for no reason at all, it can last from 1 to 7 hours.

I have 140 beats per minute heart rate, breathlessness and I am unable to lie down due to fluid in my lungs, and chest pain. It feels very similar to heartburn.
