I have been a platelet donor for about 5 years. About 5 months ago my pulse started skipping, I have had a 24 hour ecg monitor. I was told I was OK. The blood donor unit will not take my platelets now as when they checked my pulse it was skipping. I had another ecg at my own doctors and again I am clear. Is there any chance my heart rate will return to normal? and is it possible that donating platelets caused the problem in the first place. I would like to continue to do so if it is possible. I am 72 years old and quite active, play golf and walk regularly etc.
