I have had afib and high blood pressure for will over 20 years, long beffore having to wear a mask . I too think my rise in BP is totaly related to the white coat syndrone. I have no idea what triggers my afib which can last from less that one minute to well over 2 hours. I .
take my BP first thing every morning. Every two weeks I send those charts my my PCP. Most times my readings are in the normal range and we do not get exicted..I self monitor my health every day and know when my afib is starting. If you need, carry a little note bood with you to record notes when you think bp and afib are starting. If you are not sure you are having en episode, write it down anyway. Keep your PCP informed.
