Maybe: Thyroid deficiency can be a factor but you're getting supplementation so it's unlikely you're extremely low. Something else is going on. There are too many causes to list, but some could include: uncontrolled diabetes, dehyration from any cause such as persistent diarrhea or vomiting, infection/fever (typhoid, in particular, causes slow heart rate), Toxic exposure/poisoning, spurious measurement.
