Tachycardia

Hello to everyone, I'm waiting to have a sleep study. The problem is that I woke up 2 times every ight and some times with a tachycardia. I already had an ep study for it with ablation, but still I have this problem. Would be glad to know if someone of you experiences this problem and how it is, how long it lasts the episode etc. I woke up suddenly with heart rate around 140/150 and it lasts 1to5 minutes.

You might consider getting this Kardia Unit. When you are having these episodes you can record an EKG on your phone. It can be a record to show your doctor..or..if it is really bad, you can transmit the EKG directly to your doctor.

Are you worried the tachycardia will mess up the results of the sleep study? If so, I doubt whether that will be true. Even if you have episodes and they wake you up, that won't interfere with the data about what is happening while you are asleep, and those are the data that matter for a sleep study.

What kind of sleep study will you be having? At home? In a sleep lab?

Thank you for your answer

@LSAT I have a little device "gima PM10", I registered several episodes, but 2 cardiologists are in doubt, one says it's svt, another one says is sinus tachycardia, maybe kardia would be more accurate

@Miss Emerita no I'm not worried about it, I would like to know if my hypothetical sleep apnea causes these episodes of tachycardia. The ep study is the one at home.

5 years ago I was experiencing something similar.

Only mine happened during the day. (175 BPM or thereabouts for an hour)

Occasionally at night I would have a racing heart and wake up from sleep. Not as high as 150 BPM, more like 110 BPM, and it would last for about 5 minutes or so.

I also had two cardiologists unsure of exactly what type of tachycardia I was experiencing. One said SVT and the other said Atrial tachycardia. I never did figure it out.

Two doctors who were dealing with me (one a cardiologist the other an ER doc) disagreed over whether the cause was OSA or not. The cardiologist did not think OSA was the cause because normally OSA results in bradycardia not an SVT.

The ER doc suggested a sleep study which I had, and the study indicated moderate OSA. No abnormal heart rhythms were detected during both the initial sleep study and the titration study, however.

I have used CPAP for about the last 4 years and not had any significant tachycardia in this time, the odd run but nothing like before I am grateful to report.

But of course not every single person with SVT or sinus tachycardia has OSA. In my case though I am sure the two are connected. A good reason for me to use CPAP!

Hope this helps.

It wouldn't be impossible for a prolonged obstructive apnea event to put enough stress on the body overall to cause a rapid increase in the heart rate. So not impossible but in all honesty....not very probable unless you were having a lot them back to back for a prolonged period of time. Not to get it to 140 and above rate.
Hold your breath for 30 seconds....does your heart rate change? I doubt it. Now if you did that for once a minute for 15 minutes...it might change.

So IMHO...while not impossible....not probable given your history of ablation which tells me other stuff is going on if you needed an ablation. BUT untreated sleep apnea can sometimes be responsible for need for ablations....so again not impossible and it is good that you are at least checking to see if sleep apnea is a factor or not.

How's that for saying "maybe"

Hello Arlene thanks for your reply, today I had a tachycardia while I was sitting, I registered it and the cardiologist said it was sinus rhythm so he said it could be everything from my anxiety (my heart rate skipped very fast to 140), so now I'm really confused because everyone say something different, I had an ep study thinking to fix the problem but still I'm.at the same point

Thank you, now ialso think that sleep apnea is not responsible of my episodes
