I have been discharged from hospital after three days. I went in with severe and irregular palpitations which went on for approx 12 hours. I was told my troponin level was 280 and went to cardiac ward. A second reading some hours later was 302. I was treated with blood thinners and given ecg and chest xray. I was put on ambulatory heart monitor for 24 hours. I am 65, fit non smoker, moderate drinker 5ft 10 under 12 stone. I had no chest pain or any other symptoms except for the palpitations. This has not happened before. The palpitations corrected themselves while I was in the waiting room before triage. On discharge I was given bisopropol 1.5 mg. How do those tripping readings relate to the ones I see online which give high as greater than 30 ng/l
