Went to the hospital the other day cuz of spiraling anxiety and chest discomfort and they newly diagnosed a right bundle branch block. Been obsessively checking my mobile ekg. Can someone help me understand this reading? My anxiety has been horrible since increasing my SSRI. I spiraled worried I might have been having an MI. The new bundle branch block diagnosis isn’t helping 😭
35 y.o. Female. No hypertension. Had my one and only afib (with rvr) episode last year after starting an SNRI. Otherwise, my holter monitors have always been normal sinus or sinus brady, so this new development is concerning for me 😞
