I am still awaiting testing for these issues - but would like to hear if anyone has any idea on what could be happening here.
Female, young adult, otherwise healthy. I have been having issues with fast heart rates, nausea, sweating over the past few months on minimal excertion. Eg- I’ve measured my resting to be 60-74 (lowest 54 from what I’ve seen). Upon standing this will raise above 100. Walking around the house 110-120, and walking down the street for 5 mins 150-180 (I do not get out of breath with these high numbers when just walking). I’m just not sure what could be causing this?
A couple things I would like to ask however - sometimes upon standing the HR will increase to well above 140 without moving. This is when I will become nauseas, palpitations, sweaty and fatigued, and feel like I need to sit down. It resolves itself when I do.
Another thing I’ve noticed happening sometimes is I’ll stand up and my heart will slow right down - slower than what it was when I was sat. While slow, I’ll have really strong palpitations and a thumping headache. This goes off quite quickly - with my hr speeding back up to the standing 110-120 within 20secs - 1min. Any idea what could be happening here? (Eg; sat; 73. Standup - down to 58 with headache and palps for about 20 secs, but quickly increases up to 130 walking out of room - headache goes away, palps stay sometimes)
If it’s any help, we have a family history of Sick Sinus Syndrome with Brady and Tachy issues (not sure on the specifics) ; and my BP sat up in bed is often around 95/49 - not sure if this info is of any relevance. Thanks for your help! :)
