I do not know the answer to your specific question but I do know there are consumer 6 lead ECG's that one can purchase [1] for much less than the amounts you are talking about. Some of them are stand-alone [2] and some require a cell phone.
For 10 minutes in April I was seeing double.
There are many things that can cause this unrelated to the heart and should be looked into by a doctor. I am not a doctor and this is not medical advice. Even staring at a screen too long can cause temporary diplopia and there are nutrient/mineral deficiencies that can exacerbate this unless you mean you were going cross-eyed and there are multiple things that can cause that. Don't panic, talk to professionals. I personally would start with an ophthalmologist and nervous system specialist (that is one person).
just an example, there are many of these, not medical grade but don't need to be for your doctor to see if something is off.

Do you have advice on how to get the actual data?
My second question for non-US readers:
Does $9,000 seem excessive?
Background: For 10 minutes in April I was seeing double. Fearing that it was a transient ischemic attack, MDs ordered lots of tests. The heart monitor was to check for arrhythmias that could cause a clot. I was surprised that the study found ventricular tachycardia; see: https://www.fraserphysics.com/page2_ecg_report.pdf
Coincidentally, I have been thinking about ECGs and have written code for analyzing them; see Section 6.3.1 of my book at https://www.fraserphysics.com/book.pdf. My third question is for anyone who knows about ECG analysis technology:
Is the analysis technique I describe in Section 6.3.1 interesting/novel?
PS. None of the test results are very disturbing. I believe that my event was related to the migraines that I have all too often.
