If your physician has not already, he might--on your request, run a number of (indispensable) blood tests, namely, a general metabolic panel; CBC with differential & platelets; iron, TIBC, & Ferritin panel; & a full thyroid panel with TSH.

Most physicians--& certainly cardiologists, are completely unaware of--or under value, the role of diet (including supplementation) & blood nutrient levels...can & do play in heart function. For example, I've yet to meet an M.D. clinician who is aware of the role of...copper in heart rhythm. Copper deficiency (linked to levels of iron & zinc, which are complexly related) can cause...arrhythmia--& almost NEVER is diagnosed by physicians or cardiologists (they are quick, however, to prescribe or increasingly to recommend aggressive interventions like catheter ablation (which does NOT cure arrhythmia...but does generate about an $80,000 bill for an half-hour procedure).

And copper, iron, & zinc are only some of the many dietary & environmental factors that physicians might address & consider. Sleep position, for example, plays a role in heart arrhythmias too (when was the last time your physician/cardiologist asked you whether you sleep on your left or right sides or on your back--or face down? Never...would be my guess.

Yet there is a sizable scientific (peer-reviewed) literature (don't believe me: do a search on PubMed--it's open to the public)...suggesting that left-side sleepers are more inclined to experience...arrhythmias.

Net-net: There are so many environmental & even behavioral factors clinicians can & should consider & investigate...before proceeding with pharmaceutical and/or surgical interventions!

All the best & stay safe 🙂
