Ok so I have noticed that in the last month or so my heart rate when resting is around 60-65 which for me can vary. at times its in the 50s which has been the case for the last 3 years or more. had all kinds of tests and drs can find nothing wrong. I was told I had MVP(mitral valve prolapse) t the last tests I had done showed it somehow healed itself? (i was told it can only be fixed by surgery) more than one dr confirmed it.
anyway now when I walk a faster pace(like walking the dog) today my heart rate shot up to 177bpm(fitbit) I manually checked it and it was correct. I cannot even get my heart rate up that high when working out in the house. could it have something to do with the heat and humidity?? I have no other symptoms no chest pain, no dizziness,no nausea or vomiting, no headache, nothing. usually it takes me a hell of an effort to get it to 150 so what gives? I have no issues getting it to come back down to normal either.
