I suffer postural hypotension. Not only does my blood pressure drop when I stand up sometimes, but my heart rate also jumps significantly to counter this
It’s happens more when I am dehydrated, and if my heart rate is particularly low before I stand up
I went to see a cardiologist about it, as I also get a ton of ectopic beats. All of this has happened since I got fit after a lifetime of unhealthy living
Anyway cardiologist scanned my heart and told me it’s structurally sound so absolutely nothing to worry about.
As above, the biggest danger is hurting yourself from falling over if you take a dizzy turn.
