Svt

I had a successful ablation for svt in May 2019 & a PM fitted  in Sept 2019 for bradycardia . Over the past few weeks  I have noticed my heart attempts to go into svt again, all the old warning signs are there but so far the symptoms have lasted at most 20 seconds or so without  going into a full blown svt. Has anyone else experienced this. I'm getting  a tad breathless with little  exertion at times.es as well. A tad awkward to approach pacing team & GP in the current climate crisis. Any feedback will be gratefully received  thanks.

Don't be shy, don't wait, this needs to be checked

Hi: I think you should put aside your understandable reluctance to pester your EP team.

If you have a remote monitor, get a transmission sent and then call them the next day to see what your PM is recording.  If no remote monitor, get in touch, explain that your symptoms are exactly the same as the last time you had a documented SVT and ask them for a clinic visit (my local teaching hospital is half-empty on the non-Covid-19 side).

Short-lived episodes of SVT can quickly become persistent, and persistent SVT can quickly put you into heart failure (even if you were 20years old).  And some SVT *can* put you at risk of SCA - depending on your vent-rate.

Don't delay, this is potentially serious.

Best wishes.

I understand your reticence to visit doctor's offices at this point but perhaps a video conference would be useful?  SVTs aren't usually dangerous in the short term, without other issues as well.  Medication (beta blockers or calcium channel blockers) can mitigate most risks.  Your doctor should know if you're in immediate danger and can balance the risks of an in-person appointment vs. waiting until the risk is lower.  In any case, a call to your cardiologist/EP is in order, sooner rather than later.

Just had a very similar experience. Had PM implanted Sept 2018 (because of sick sinus syndrome) and started with minor SVT in Nov 2019 and was put on a beta blocker which stopped the SVT. Then, starting this past March, SVT started again so I transmitted my readings to the dr and called them to discuss what's been going on. Dr. said that the recent SVT episodes were caused by noise coming from my lead which caused my pacemaker to kick in when not needed. (Readings look different when this happens.) So, I had to go in and they changed my pacemaker settings. It's been a couple weeks and haven't had another SVT episode until just today. The cause is that there may be damage in my lead, but they won't address it until I'm up for a battery change and even then, they won't do anything unless it's life threatening. 
 

Bottom line, at a minimum, call your dr. 

pacing check

Hi all, 

I managed to get in for a check up with my Pacing team today,who did a full interrogation.

Whilst they could not find any events of SVT other one which lasted for only 14 seconds with a HR of 220bpm, probably due to the sensing setting, they are going to send a full report to my cardiolgist/EP with more requent monitoring.

They also found approx 600 pvc's with no significant delay so it looks like I will be living with those for sometime. Nice to know I'm not at any life threatening risk.

Thanks & Best wishes everyone.

Glad to hear and thanks for the follow up

Glad to hear that there's no immediate serious problem.

Many thanks for posting the follow up information.

Best wishes.
