I just came from restaurant and at the restaurant I was eating my food and I noticed that my heart started beating very rapidly I didn t do any physical activity I wasn t nervous or anything like that my heart just started beating very rapidly to the point where I can feel it if I just placed my hand on it. I went out to dinner at around seven and it s still doing the same thing and it is now 10:30. I feel the heartbeat more so towards my throat, like the bottom of my throat. if I touch mycollarbone I feel the heartbeat there. so I was wondering what could cause this and how I could stop it because it is continuing to beat rapidly and it s uncomfortable please help me Dr.
