What causes heart fluttering and dizziness while having mechanical aortic valve?
Patient: I have experienced on and off heart fluttering over the last couple of weeks. Had some dizziness once or twice. I think it may be caused by caffeine and/or stress, perhaps low blood sugar. I reduced my caffeine intake. This occurrence has happened twice before in my lifetime and it eventually went away. The first Cardiologist did check me out and prescribed a beta blocker and the second Dr. checked me out with a monitor and told me that it will probably would go away and it did. I have a mechanical aortic valve and take warfarin. Doctor: Hello,  I would explain that your symptoms could be related to ectopic heartbeats.   As the Holter monitoring has not shown any serious cardiac arrhythmia, there is nothing to worry about.  Hope I have answered your query. Let me know if I can assist you further.  Regards, Dr. Ilir Sharka, Cardiologist
