After Eating A Bowl Of Chips And Bean Dip, I

After eating a bowl of chips and bean dip, I fell asleep. I was halfway awake and on my side when it felt like my heart stopped beating and blood was whooshing through my heart. I jumped up and my heart started beating normally again, but then every so often I will get that whooshing feeling and it feels like my heart isn't beating normally. I have been to a cardiologist who diagnosed tricuspid regurgitation moderate/severe), but he hasn't prescribed any medications, etc. Please advise! I'm scared to go to sleep right now in case I don't wake up!
