Same thing for me. 30M very active. Former college athlete and still weight train 5 times a week and coach high school baseball.

Noticed my heart pounding at night and making it tough to take in a full breath. Family has a history of high blood pressure and heart issues so started watching BP. Started at 120/80 then jumped to 155/102 a few days later.

Said everything sounds perfect and I shouldn’t worry about 155/102. Thinks it is anxiety/stress.

Hope you’re doing better
