ECG call back

So as my journey has gone I have gotten a call back from my family doctor that I need another ECG.  I was born with a slight murmur but over the years doctors have said its not a big deal.  I'm really hoping that's what this is about.  As terrible as this will sound, will this derail my progress?  I meet the internist very soon so I'm hoping I will get the answers, however, it was my GP *****quested it and not the bariatric centre?  I'm a bit confused.  Just like my ultrasound call back (gallstones), my doctors office was horrible at giving any info, the girl that called knew nothing.

So my friends, anyone have any issues with ECG that held them up?  I'm with Hamilton if that makes any difference.

Thank you!
