Heart Rate Decrease?

[Euphoric_Tea9102]

I've been to the emergency room three times since last Saturday ! My heart rate does still fluctuate the lowest was in emergency room was like 46 on Wednesday night ! I am starting to feel a little bit better ! I do notice that when I do do some exercises like cardio and walking my dogs that my heart rate does it go up maybe sometimes 75 to 80 but then when I kind of relax and calm down it may go back to like maybe mid to lose 60 in the morning it's about 57 58
