My bp sometimes goes very low. 96/50 today and i got dizzy, shaky hot & clammy. i sometimes get palps too. only 32, mum had heart attack in 40s and pe?

It is unlikely that: your low blood pressure and associated symptoms are related to issues that would result in heart attack. The dizzy, clammy hot and shake are all a response to the low blood pressure and your body's attempt to correct it by releasing the hormone adrenaline. I suspect you have dysautonomia. (autonomic dysfunction) You should be evaluated for this diagnosis.
