Hi iam 33M
My resting heart rate in the early morning and before going to bed will be around 72 bpm
But during working time(mind sress job) it goes and fluctuates even till 84 -92 and comes back when work is reduced
Echo Ecg other tests all came out normal but this happens..
Sugar BP all normal
Have anxiety issues though
1) Is this normal
2) Can an elevated Heart rate say 90 cause Left Ventricular Hypertrophy?
