Any medication involving the thyroid can take time to settle down and it can take a while getting the balance right. The slow heart rate is likely related because the thyroid plays a big part in blood pressure/heart rate. I would just mention this to your cardiologist, make them aware your heart rate is getting low. If your blood pressure is dropping due to this, then you will feel dizziness and shortness of breath. Maybe they should lessen your dosage.
