Re: possible dodgy ticker..
If they find something dangerous you would of been contacted. When I have these tests, my GP and Cardiologist would certainly tell me if it was an issue. They are not going to risk your life.
I am going to have a Holter monitor on the 6th of January, and then be seeing my Cardiologist on the 20th January to review the results.
If the ECG and blood tests don't show your heart doing anything dangerous then I would not worry to much until told otherwise.
I get PAC's (skips and double beats) Cardiologist even said he could hear a murmur. But was not phased or concerned. And said we will do the Holter Monitor and an echo when I see him on the 20th January.
I said I am not going to have a heart attack or drop dead, and he laughed and said "no"
So it made my stress levels lower greatly. If it was urgent, then you would have been rushed more to see the specialist.
