    Tachycardia or pounding pulse when lying on left side

    Cool. Mine is about 20. I also have a mild pectus excavatum, which I thought it might help with understanding what is going on here. I never had tachycardia, but during the first 6 months of symptoms I slept with about 90 bpm. Now I only get the pounding. Do you also have pectus?

    Tachycardia or pounding pulse when lying on left side

    I am confused now. You started this thread with the pounding happening when lying on your left side. No pounding when lying on your right side. Now you write it's consistent when on your right side and very occasionally on your left. Also, what is your BMI?
