Yes taking Nitric Oxide, for blood flow, now for about a week, and now my chest feels like phone vibrating in my chest above my heart, and just had a check up...everything good, but blood pressure was a little high, due to job!!
Just reading all of these posts makes me feel so much better. I suffered a sudden cardiac arrest in 2006 from extremely low potassium and acquired long QT. For several months afterward I had the chest vibrations. When I asked the electrophysiologist about it he admitted that he was stumped, and he said he had even experienced the feeling himself! It went away on its own for a few years, but lately I have been having episodes again. Every time I mention it to the electrophysiologist, they do a download of data from my defibrillator and tell me “no significant arrhythmias”. The EKGs are always fine, the blood work is always fine and the doctors are always left scratching their heads. Along with the vibrations I get palpitations, but my pulse is never more than the low 80s and my oxygen is always 97 or 98 and blood pressure is always fine. It is really annoying and very scary. Thanks to all for sharing. It is good to know I am not alone in this.
Aug. 14 2014 - Still having the vibrations, has been worse since June. Doctor can't find anything yet, I have a irregular heartbeat at night but she didn't think it was dangerous. Doctor put me on mild metaprolol to see if it will help. So far I don't notice any change..it just happens some nights & some nights it don't. Does happen on occasion during the day but not usually. Frustrating & annoying.
Have had these for decades. I always think of it as a sudden burst of coca-cola fizzing in my chest. Happens anytime but not while sleeping. Lasts two or three seconds and I can't breathe until it passes. My doctor thinks it's a slight build up of blood in one chamber of the heart which suddenly releases and causes that sensation. She says it's harmless, but I do wonder. I also have a supposedly harmless heart murmur.
I have gotten those occasionally, never really afraid of them bc I just thought of it as a weird spasm like a shiver or "pins-and-needles."
But I did got to a Naturopath who said that my diet - although generally healthy - wasn't right for my blood type and therefore the foods I was eating were clogging my blood in different places- not blood clots, but clumps where the blood cells agglutinated bc of lectins being registered as foreign species in my bloodstream, and thus attacked upon entry. So I think the bubbling or "buzzing" erratic movements are caused by blood flowing in places where it is agglutinated and too thick to pass through normally: fights to get past the blocks and therefore ends up sometimes stretching skin outward to get past. If its happening around your heart mainly, not your pulse, then that's a strong sign that it is not heart/pulse problems, but very possibly agglutination of red blood cells or other types of clogging in the blood stream. (Note: agglutination is not the same thing as gluten, only means coagulation and congealing; so red blood cells are like an almost-solid mass, making blood flow difficult.)
It makes sense that dehydration would exacerbate it; I've had that before and I think it's because water will dilute the blood and help it flow faster and easier, also keeping you healthier and immune system strong so better able to fight off the "foreign" objects entering the bloodstream. Without enough water, blood runs thickly and more difficult to get past the areas of agglutination. (Sorry I know I said that already, but I just thought I'd repeat it here for illustrative purposes.) Also if you're hydrated you think better and aren't as likely to panic, so that's probably another indirect reason for why it's easier for you to handle it when you're hydrated. And then there's also the fact that you aren't as likely to experience that when you've had enough water, bc your blood will be thin enough to flow easily.
Do you ever get auras/fainting/dizzy spells when you're less-than-adequately-hydrated? That could be another indicator.
I think I'm experiencing this too, scary. 40 year old female. I did have more than normal caffeine today and I'm thinking maybe this has something to do with indigestion too. I seem to be burping more but it could be the anxiety that this brought on. I feel the vibrations in my arms too when I'm laying down, I have to change positions. Makes me feel like a nervous Chihuahua.
