question: I have grade 1 diastolic dysfunction. I exercise regularly and am quite fit for 65 years. I eat well and drink a couple of glasses of wine daily. Why does my heart flutter with dizziness occasionally? Occasionally meaning 1-2 x daily or maybe never for a few days in a row. Otherwise I am very healthy. I wear a fentanyl 50 mcg patch daily and take oxycodone for break through pain 1-2 daily as needed, as a result of grade 2 spondylolisthesis at S1, L1-5; severe stenosis; and severe arthritis. I keep up the good fight though! Your comments are very appreciated. Thank you.
