Inappropriate sinus tachycardia?
In September 2021, I was diagnosed with Premature ventricular contractions (PVCs). My cardiologist indicated this happens to a lot of people and didn’t prescribe any meds. This condition results in what I describe as a heart fluttering sensation. Sometimes several weeks go by without any symptoms. I’m ok with this.
However, lately I’ve had a couple of episodes of very high resting heart rate. I took the following notes:
10 July 2022 @ 10:30pm
Had episode while resting in bed where my bpm went up to 124 for a couple of minutes and then back to my normal resting heartbeats of 68 bpm.
24 Non 2022 @ 7:12am
Woke up with bpm of 139. The bpm was in 120s until about 7:30am. After that it returned to a resting heart beat of 69.
Did some research on the Mayo Clinic website and found the term inappropriate sinus tachycardia which seems to describe the two episodes above.
Can someone confirm this is the right term for these episodes? Can I ignore this or can this be dangerous if not treated?

I have a fantastic cardiologist who told me it is usually a young people thing. She tried a couple of meds, but neither could I tolerate. She said these Sinus tachycardias sometimes “burn themselves out”. My HR goes up into the 150s. Frequently I can’t even tell. I got an Apple Watch just so I could keep track of it, but decided if my cardiologist is t worried, I wouldn’t worry either. It makes life a lot easier to stop worrying.

2 ReactionsI am having same issue with my Sinus Tachycardia. And others I have. BPM usually anywhere between 111-171. Used to be mostly stress but now a few to dozen+ times a day at regular activity, light activity (like walking 14 steps to bathroom to pee and then 12 more steps to grab something from fridge to drink) it starts. Sometimes when watching a movie with the hubby on TV. Whenever, wherever. I have checked Kardia periodically and the most common one I get is the S-Tach. But I also have had psvt as well as Ventricular Tachycardia as well but those are usually too brief to catch on Kardia before they are over with so far. Which is a huge plus as V-tach is frequently dangerous if not quite often deadly in a hurry if sustained. This could be what is happening to you...maybe different types of Tachycardia. Call your Cardiologist, if you have one or your PCP if not and tell them what is going on and request at least a 14 day holter monitor AND someone to cross check the accuracy of the AI algorithm used to interpret it as the FDA announced an issue with one that is most widely used in the US that misses Ventricular Tachycardia sometimes. That is what happened to me. My Cardiologist (now former) just went off the AI determination and missed it. V-Tachy is very very dangerous so you need to know whether it ma sometimes be that or another tachycardia. Don't wait on this to call....first thing Monday AM. May just be IST but you need to know what you are dealing with one way or the other.
Still trying to get into a a dept cardiologist but no appt availability till Nov.
