I've low BP - usually 98/63 or even lower - 77/49 one morning last week. Pulse is usually anywhere between 84 and 124. Don't seem to have any problems with it except if I'm, say crouching down weeding the garden I have to be careful standing up as I go very light-headed (but this is only if I have been crouching down for a fairly long time - say 10-20 minutes or so). I'm not particularly worried about it because this is something I've had for the last 20 years or so (I'm 47). Do know my heart skips beats (sometimes it feels like a flutter then a thump). Apart from asthma (got a Salbutamol inhaler for that) I'm quite healthy. Just curious for what might be the cause.
