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.

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.

I am also not a doctor. I have an appointment with a specialist MD. My PCP was initially alarmed, but after some research and consultations believes that I am not in immediate peril.
Unfortunately the devices that those links point to would not provide 24 hours of continuous data. The data that Phillips won't give me is a continuous record of about 720 hours with a few small breaks. The interesting event was one 2 second interval in the middle of one night.
