Sleep Study Results and Tachycardia
#1
Sleep Study Results and Tachycardia
Hi 
Sorry to bother you. For almost a year now, I've been suffering with these arousals on transition to sleep, whereby just as I'm drifting off, I awaken on a sharp intake of breath or an sharp exhale with a raised heart beat.
I have no conscious anxiety playing on my mind, but my body constantly wakes itself up in this state. 


I do have moderate OSA and have had great success with a MAD up until the development of these events. I've tried a MAD as well as an APAP machine, but neither seem to alleviate these arousals unless I take sleeping medication (I no longer use my APAP as a result) 

I've just had a sleep study which I used my MAD during and it does confirm my AHI is low, which is good. The Sleep specialist didn't have much negative to say, but having since received an email copy of the study I've seen I had 39 tachycardia's during the night.

I've attached the full sleep study below (apologies but my phone won't let me post the photo in yjr article and my laptop is undergoing repair atm) but was curious as to whether anyone thought this was unusual, or is this something that is normal in someone having apneas?

I do intend to ask my sleep specialost about this when I have received his report, but did anyone have any feedback as to whether this seems normal or is something that might be causing issues?

Any feedback would be hugely appreciated!

RE: Sleep Study Results and Tachycardia
This is an issue best discussed with a cardiologist -- or even better, an electrophysiologist -- as tachycardia may be caused by an underlying condition, drugs, supplements, or even dreams. It is not something that can be regulated by changing the settings on your cpap device.

In my case, nocturnal tachycardia led to the discovery of an arrythmia which necessitated medical intervention (implanted pacemaker/defibrillator) and the use of the antiarrhythmic drug amiodarone along with additional magnesium.

For your own peace of mind, check it out.

Best,

Steve

Thabk you! So do you think my 39 tachycardias looks high/something that should be investigated further?
I wasn't sure if some degree of tachycardia was considered normal?

RE: Sleep Study Results and Tachycardia
Impossible to tell without a detailed history, knowing co-morbidities, drugs, supplements, violent dreams -- pretty much why no forum answers diagnose medical issues from afar.  

Generally speaking, "For adults 18 and older, a normal resting heart rate is between 60 and 100 beats per minute (bpm), depending on the person's physical condition and age." But a statistical normal is worthless for a person having medical issues.  It could even be elevated from the stress of a sleep test. 

But, like I said -- for peace of mind and to prevent real problems in the future, check it out. Call them and see if they are concerned -- and if not, you still might want to do a stress echocardiogram. 

Remember, your health is your business and your life, and most physicians may gloss-over symptoms which are in the high-normal range until they become problematic. Something you do not want to hear in the emergency room. 

BTW, my heart rate is paced at 60 with the defibrillator triggered at 127. 

Just noticed you are in the UK -- so book the appointment as early as possible.
