I have a heart murmur due to rheumatic fever aged 7. I had 2 episodes of palpitations several years ago but nothing was found (put down to stress) and had nothing since. I have been very fit, active and well, working full time until a year ago, on no prescribed medication but take some supplements, so this episode and its implications has been a shock to the system, I am not sure how long symptoms last or if my dizziness and lightheadedness is due to the meds. I also have no appetite and am losing weight due to digestive discomfort. My twice daily home checks show normal BP, pulse rate and rhythm. I guess I'm looking for some reassurance. I have not had the oportunity to talk about this. I'm now awaiting monitor and scan.
