Elevated heart rate during sleep?

[esender]

An issue I continue to have is, no matter how much sleep (deep or light), I tend to wake up very groggy. I think I found a clue as to why and maybe it's my elevated heart rate during sleep. See the picture here:

I tend to have low-ish blood pressure and heart rate during the day, I exercise and sometimes take microdoses of Melatonin. 

What can I do to keep my heart rate lower during sleep and perhaps get that U shape to my heart rate graph consistently?

Tachycardia may not have any symptoms, but it's not something to ignore if it persists.  Fitbit makes this easy to monitor.  It is important to know that elevated heart rate can indicate a risk factor for cardiac arrest, stroke, and sudden death, among other things.  The line-in-the-sand is an average resting heart rate of 100 beats per minute.  Since Fitbit users are all about preventing medical intervention, if your resting BPM is of concern to you even at a lower level, re-evaluate your cardio and tighten up on a heart-healthy diet.  It appears cardio exercise (jogging) seems to have nicely lowered your BP.  Focus on consistent cardio over extreme and track your resting BPM.  After a reasonable period of time, see what the numbers tell you to decide where to go from there.  If your BPM continues to rise, there are tried and true medical solutions out there to help with this.  Good luck and stay healthy.

It’s my sleeping heart rate that is the issue. Most nights I get a low score because it doesn’t stay below my normal heat rate. Last nights got was 4%. My graph is never hammock shaped more like hiking in the Rocky’s at high altitude! What can I do to lower it? There is no expandable option for this reading on the app. I have premium.

How is your average spO2 and oxygen variations? Tossing and turning percentage, and your sleep cycles? It could be a lot of things.

For me I take a medication at night that induces tachycardia, so my above resting BPM is usually 70 to 100 percent. I take a beta blocker in the morning that restores my heart rate to normal. My restoration and HRV tanks because of this. It doesn't help another medication I take is also known to induce lower HRV scores. Often single digits.

I run 3-4 times a week and strength train 4. I'd consider myself relatively healthy otherwise
