See cardiologist. This is not something that can or should be managed online. See a cardiologist who will follow and make appropriate recommendations for monitoring and therapy.
Heart problems. I would expect it to be scary. Your heart is being extremely stressed and your circulation is not keeping up. See a doctor immediately.
