Hello? I am 36 years old female in ok health. I have cardiogenic neuropathic syncopy and a the largest pfo my cardiologist has seen. My cardiologist has dismissed me and let me go back to my family dr. I have not seen a pcp in about 4 years. I take no mess. I have been experiencing dizziness and lightheaded like I m going to pass out for about 48 hours now. I unfortunately am not able to just rest. I have been taking in a lot of fluids and feel better for about 1 hour then worse again. What is this and how do I get it to stop. I have also been having what I would describe as gallops. With my heart beats. And when I get excited or worked up it becomes much more pronounced.
