Does anyone know what could cause slow heart rate in combination with a chill / cold feeling?
I've been dealing with this for some time. Sometimes I have inappropriate sinus tachycardia, other days I have this chill and cold feeling with a slow HR. I take thyroid medicine and my levels and all blood work are always normal.

short health history:
47yo male
1. I'm on Xarelto for blood clotting disorder.
2. 2015 and 2019 had DVT/PE.
3. 2017 - Had one AFIB incident, put on Multaq until this year and taken off due to no more AFIB.
4. Take Xarelto 20mg, Bystolic 0.50mg
