I have afib and that was recorded on my first try. Since then I have had svt and wide Q and supraventricular ectopic. It has cleared up after initial change in dosage. There is nothing else I can take for pain. My latest dosage of oxycodone 5 mg left me struggling with confusion, breathing problems, and nausea. For other pain not covered by LDN I use pain patches, lidocaine 5% by Endo, as well as lidocaine-prilocaine cream and my spinal cord stimulator. Also pain management doc does a great job at needed procedures. It's waiting on Workers Comp to approve that drags my pain out.
