I've been noticing something strangewhen I'm lying in bed, I can actually feel my heartbeat, and while my heart rate seems normal, my body feels like it's shaking a bit with each beat. I got my echocardiogram results, and it shows a myxomatous mitral valve with mild MR, with measurements of LV ID at 5.7 cm and 3.8 cm, IVSd at 0.8 cm, LVPWd at 0.8 cm, and an EF of 60%. The doctor mentioned my left ventricle is slightly enlarged but not dangerous. But here's the thingwhen I stand up quickly from lying down, I get really dizzy. Could you explain what might be going on and what I should do about it?

When you suddenly stand from a lying position and feel dizzy, it could be due to a drop in blood pressure known as orthostatic hypotension. To help alleviate this symptom, you can try increasing your fluid and salt intake, wearing compression stockings, and slowly transitioning from lying to standing positions. Additionally, you may benefit from medications such as Fludrocortisone to help increase blood volume and improve blood pressure regulation. It is important to discuss these options with your doctor to determine the best course of action based on your individual health needs.
