Step away from the Pulse OX monitor! I echo what everyone else said. As someone who lived through it, try not to hyper monitor yourself.
So I can stop stressing over it*
My average resting HR during the day is usually 62-64 and at night before bed its 55. This is really scary for me, hence the reason I'm up late many nights. I feel like I have to shake my leg or keep moving even when reclining in bed, as being still seems to bring awareness to the slow beat of my heart.. I've been battling severe anxiety for the past 6 months and I constantly worry about my HR. I research a lot and most of the information regarding low resting heart rates is pertaining to people who are very fit and lead extremely active lifestyles. - Not the case for me. I'm 27, 5'1 and 175lbs. For the past few months I haven't been too active, I developed agoraphobia after having a panic attack in a store that spiked my HR to 160 and I pretty much became home bound for a good 2 months... After therapy and thyroid correction medication I am slowly becoming more like my old self, however I still have anxiety about my health, and my main focus is always my heart. I did 3 different holtor monitors, the most recent was over Christmas for 21 days monitored 24/7. My cardiologist said I have tachycardia and bradycardia but a normal sinus rhythm. And told me not to worry as I am fine. - I still worry though. It's so frustrating. I remember one night I fought sleep so hard I stayed up till I saw the sun, because I feared my heart rate was going to drop too low in my sleep. - my therapist told me to remember and tell myself "this is my heart rate, it has probably always been this low and it probably does drop lower in my sleep, but every night I go to sleep and every morning I wake up, just as i have for 27 years, And it is very likely that when I go to sleep tonight, I will wake up in the morning." - though its scary to think about, its true. I just wish my brain would get the memo so I could stressing over it.
Thanks for the response. Since I messaged last it has gone down more. Now when I'm resting it can hit 44 and when i start to doze i notice it hits 41. I think it even hit 39 at one point. The whole time my oxygen is still in the 90s. It has gone down to 93% but so far this eve the lowest its gone is 98%. Makes me scared to sleep. o.O
Healthy people are born with a certain resting heart rate. Sometimes, even in those who are not at all athletic, this rate is very low, and as long as there is no heart disease going on and they can do all their normal activities, it's fine--just the same as being born with blue eyes rather than brown, for example.
As a woman aged 41, you are at less risk than a middle-aged man. That's just the way the risk for heart disease works.
Should you be worried? Probably not.
However, since you are concerned, it would not hurt a bit to get a baseline heart check from your friendly local doc. It's always good to have something to refer to.
