I am a 38 yo female who has been experiencing heart palpitations my entire adult life.
I have had Holters, ECGs, and echos, and only PVCs and suspected inappropriate sinus tachycardia have been diagnosed. I have learned to live harmoniously with the occasional flip-flops and tachycardia.
However, I have had these episodes of severe heart palpitations that feel distinctly different from the usuals. Very occasionally, maybe once every 3-6 months, my heart will acutely speed up, then flip-flop like a fish out of the water. Not a small fish, a really large, angry fish. The sensation is very intense. These events also last longer than I would like - the usual PVCs are a quick one or two flippity flops, but these persist.
When these occur, I get dizzy and I start to see black and stars. I have never actually fainted. An event occurred today, and after realizing that my heart rhythm was not normalizing after about 5 seconds, I started to walk down a hallway to ask my receptionist to call an ambulance. I had to clutch the wall because I felt unsteady. I was certain I was going to die.
Then, as usual, the irregular rhythm stops and I feel a sudden rush of blood to the head and hear whooshing in my ears. My heart is usually quite tachycardic afterward, but it is hard to tell if that is part of the irregular rhythm or the panic that sets in when I believe I am dying.
These events occur when I am at rest, they have never occurred during physical activity. They almost always - maybe always - occur in the days leading up to my period.
Because these events are so infrequent, they have never been caught on a device. Doctors keep telling me my heart is structurally normal and they are probably PVCs. But they sure do not feel like PVCs.
I haven't touched caffeine in 15 years, I don't smoke, I drink a few beers once or less a week, and I exercise at least 5 days a week.
Can anyone relate? They are super scary, and have made me fearful of situations in which I may be trapped when I have an event occur - public speaking, driving, even just being alone.
