That "dizzy rush" might have been caused by an over-production of hormones, such as adrenal hormones, which can over-excite the heart and cause higher blood pressure, among other uncomfortable symptoms. So.... first you feel the adrenal rush and then your over-excited heart goes into a rapid and/or irregular, erratic heartbeat.
MRI showed slight dilation of the right atrium and ventricle ... Any ideas what causes this dilation?
Over time, excess hormones, such as the adrenal hormones, can be damaging to organs and glands, including the heart.
OTOH, it takes a lot of skill to properly do an MRI and to interpret it. A slight tilt in your body, or with the MRI wand, during the MRI, can make a big difference during the measurement process, IMHO.
Did you get a copy of the MRI summary report, showing all of the measurements and evaluations? What did it show about the measurements of your right atrium and ventricle? How experienced was your MRI technician?
In my non-professional opinion, over long periods of time, excess body hormones will continue to do their damage.
Can I make it better or reduce it in any way?
I can describe what I have done to greatly improve my diluted heart and health. Basically, I live as healthy as I possibly can, including diet, exercise, avoiding things that cause over-production of hormones, and I take the most effective medications that protect me by blocking excess hormones.
My health and heart disease is much worse than yours, so you would probably not want to, or be willing to go to my extremes, but you might get some ideas from reading about what I did.
If you are interested in reading the major changes and restrictions that I have done, to significantly improve my health and heart disease, please glance thru my "Heart Disorders" thread: What I have done to survive Heart Failure & AFib with a high quality of life.
