<p>[QUOTE=&quot;Grumppy, post: 11931847, member: 54431&quot;]As I noted in my OP, Its been a long time for me but as far as I know, normal heart rate was always 72... text book. It can vary without much concern but that was always the rule AFAIK. </p><p>There have been so many things to change since the 80&#039;s, this could easily be something that I am unaware of. CPR has changed 3 or 4 maybe 5 times over the last 40 years. So it likely that heart rate has too but I still use 72 for normal heart rate. I&#039;ll look around &amp; see.[/QUOTE]</p><p><br /></p>
