Does anyone have advice about my ECG (EKG) situation?

[Buzz60]

Hello. I'm 60 years old. As part of my workplace-sponsored annual physical exam, I have an ECG (EKG), and for 14 of the past 20 years my ECG results have been normal. From time to time, however, the results have been as follows:

2000 Borderline abnormal: Poor R-wave progression
2003 Possibility of anteroseptal myocardial infarction
2006 Intraventricular conduction disturbance
2007 Borderline abnormal: Poor R-wave progression
2011 QS pattern
2017 Abnormal Q: Low electrical potential difference

I have no pain, nor am I aware of other heart symptoms. I exercise regularly (at least 30 minutes/day, 5 times a week) and I feel great.

Once, about 30 years ago, a doctor listened to my heart and asked, "Has anyone ever told you that you have a heart murmur?"  No other doctor, before or after, has ever told me he or she heard anything odd when listening to my heart.

As for my cholesterol, I have low HDL (consistently between 32 and 35), so for decades I've eaten healthily and kept my LDL low (between 80 and 100).

When I measure my own blood pressure, it's in the normal range, but when I get anywhere near a nurse or doctor, my systolic reading is always elevated (around 140, and sometimes as high as 150), which I've been told is called "white coat hypertension."

I wonder: Is it also possible to get odd ECG results due to anxiety?

Following my 2017 ECG, I went to see a doctor, and he now wants to send me to a hospital for a whole slew of heart tests using CT, ultrasound, and so on.  To be honest, I feel fine and don't want to go.

Even if were to find out something bad (?? maybe I had a mild infarction years ago and didn't know it??), what would I do with that information except worry myself sick?  And what would my doctor do with the information?

Any words of advice?
