Debating Triggering an Episode for Diagnosis
I recently got an ILR implanted in my chest to monitor for SVT after having an episode in my doctor’s office. I’m conflicted on whether I think it’s SVT or just normal sinus tachycardia as I have POTS/dysautonomia but my cardiologist (who specializes in POTS) is already calling it SVT.
Would triggering an episode be unnecessarily risky? From what I’ve read SVT isn’t life threatening it just feels scary? When my POTS is well managed and I’m not sick I have to push myself really hard in order for an episode to happen. My nephew also has SVT and has had two unsuccessful ablations, his mom had him run hills to trigger an episode which was then caught on his holter monitor and I’ve been debating doing the same.
I guess I’m just hoping to get confirmation asap and find out if I’d be a candidate for ablation. I do understand there are risks that come with ablations but the thought that I could potentially be a part of the majority that finds relief is really tempting.
So far my triggers have been high adrenaline and cardio-heavy intense exercise, especially if I’m bending over a lot during the exercise. I feel a slight pressure/buzz in my chest when it’s about to happen, and then a squeezing sensation around my heart followed by shortness of breath, dizziness, and obviously a really fast heart rate. I’ve always been able to use an ice pack on my neck and lay down, and then it stops after a minute or two as long as I’ve calmed down.
I should add that these episodes started at the same time my dysautonomia was triggered or worsened enough to become an issue. I went most of my life without daily palpitations or a racing heart beat and then I got covid and strep throat at the same time and was really really sick, my autonomic functions haven’t been the same since. Structurally my heart is healthy and I did all the normal heart tests to rule out other issues. The tachycardia also got more frequent after I started to wean myself off of my beta blocker, I assume the extra adrenaline receptors my body made to compensate for the beta blocker were ultra sensitive when lowering my dose and just causing this issue to become more obvious.
