Does the morning Tacacardia decrease in time?

I'm a newbie and am tired of the racing heart rate. Is there ytuely a light at the end of the tunnel I can hope for.

Well, if you're waking up following an event...if your oxygen level gets low enough, the brain panics and floods the body with survival (stress) hormones that jack up your blood pressure and pulse. When these are effectively treated with CPAP therapy, the events are less frequent and generally shorter so oxygen deprivation (called desaturations or desats) do not occur so the brain does have to do to full panic mode to 'wake' you up enough to breathe better/deeper. So, with effective CPAP therapy the racing heart rate improves. I occasionally have events that wake me up but my increased heart rate is just slightly increased -- nothing like what used to occur. Also, if you're also making a lot of pee trips at night (courtesy of the jacked up blood pressure), those will also be reduced -- I went from 8-10 pee trips a night to 0 on night 1 of CPAP and thank goodness those trips haven't recurred.

I am easily startled awake (unusual noise/light, phone) and my brain doesn't like that, so when that occurs I am likely to have an increased pulse. Over the past month, I am sleeping deeper so I am less likely to be easily awakened.
