Im 20 years old, I had a ecg done in 2015 and everything came back fine. I had one again on 2nd June 2017. It came up that I have a long qt, ( I have no family history of heart problems) I was left terrified and had to go back for more advice, she said its supposed to be at 460 but mine was 482, she said I'm not far over and she isn't worried but still has to refer me to get it checked out. I suffer with bad anxiety and is a nervous wreck from this, I've taken loads of medication in the past and I also take 2 asthma pumps quite a lot.. ive been on a purple one the past few months and its on the list for bringing this on could this be caused because of my pumps ? Or maybe a mineral imbalance? As soon as she seen the results she changed my pumps straight away. Im just praying it's nothing serious and is because of the medication, can I have some of your advice but please go easy on your wording as I do get really scared over this. Thanks in advance
