I get this funny sensation that my heart goes up into my throat . It almost takes my breath away for a very, very brief moment. It is a very mild sensation. It occurs at rest. I thought maybe it was palpitations but when I check my heart rate, which I can palpate readily in my throat, it feels like a normal rate and rhythm, except for maybe when I take a deep breath. This feeling used to be very rare and I seemed to notice it when laying down, but it has become more frequent and I notice it sitting up as well. I am under a lot of stress right now as well.
