Not Your Typical Question. I Have Mild MVP And Very

Not your typical question. I have mild MVP and very low LDV (41),LSV (9) and high ER-76%. I am (F,55) homebound for 5 years due to: chest pain, shortness of breath on exertion and at rest, worse when lying down, postural tachycardia, irregular heart beats, low BP in a supine position, general weakness, fatigue. Noone can explain why do I have low end volumes and all these symptoms. There got to be a connection. I only take atenolol in the mornings.
