Hi,
I am sorry to hear of your problems and current lack of Health Insurance.

I am a forum member on the Heart Rhythm forum, I wish I could be more informative to you. Likely other forum members will have things to say.
I have had various forms of benign arrhythmias since I was 15 years old, and I am now 50. Sometimes it's not very much fun when they are acting up.
Even without health insurance, perhaps you can find a Family Doctor in your area with reasonable rates, perhaps even allowing several payments. An In-Office EKG should be reasonable in cost, and may give you the reassurance you need.
Be well.
