I had both a-fib and a-flutter. I developed a-fib first, than about 2 years later the a-flutter kicked in.
I developed AF somewhat suddenly, but it was also during my first real bouts with panic disorder. Real ugly scenario. I have AF, A flutter, PVCs and SVT (rapid AF, tach of 240 bpm). Thankfully, all is under control with meds except for the occasional "flop and flutter" during periods of PMS, lack of sleep or stress. Good luck, Amy
I have had both...but afib preceded aflutter in my case.
