Im not worried about this ... i'm annoyed ... i have too much planned for the last 20 healthy years of my life for this to happen.
I know the feeling, I'm about the same age as you and something happened to me about 2 years ago which means where I used to be able to do a hilly 100 mile ride with no training, I now struggle to do 20 miles. I hope what you've got is treatable/manageable.
I nearly posted on this yesterday but hesitated because of the seriousness of the issue, but I'd like to add something to softlip's informed advice. As well as genetic and iatrogenic* causes, heart arrhythmias can be due to mineral deficiencies, potassium, calcium, magnesium and possibly others.
Magnesium deficiency is becoming more common (amount in food has declined over the past 40 years), and as the test is unreliable, under diagnosed. Magnesium is burned up in energy metabolism, i.e if you do something that uses extra calories, you will also need extra magnesium. If you don't get this in your diet (which can be challenging), you will gradually use up your reserves, though it could easily take 10 years to show.
Not saying this applies to you, but I think it's affecting me, and some of your symptoms are similar to mine. I don't suggest any drastic action, but you might like to inform yourself by looking up other possible symptoms to see if other niggles which you may have could been caused by it, to give you more information for when you see a specialist.
The BMJ paper Subclinical magnesium deficiency: a principal driver of cardiovascular disease and a public health crisis
is interesting to skim. https://openheart.bmj.com/content/5/1/e000668
A few random quotes:
"most cases of magnesium deficiency are undiagnosed"
"the vast majority of people in modern societies are at risk for magnesium deficiency"
"The existence of subacute or chronic magnesium deficiency is difficult to diagnose."
"Severe signs: Arrhythmias... especially... tachycardia with a prolonged QT interval)."
This may be irrelevant to you, but I think it's worth checking out - and based on what I've read, doctors may not think of it.
*iatrogenic = caused by doctors
