"Inappropriate Sinus Tachycardia"

Posted by warpedtrekker @warpedtrekker, Dec 13, 2018

I'm 47yo, 6'1" 220lbs. In relative good health and get around fast. My EP says I have this condition sometimes. I will be seated on my couch for awhile, then stand, and my HR has shot up to 145bpm recently with major palpitations. Also when I go up one flight of stairs at work very slowly, my HR rises quickly to 120+. I find this "inappropriate" and concerning. One day I was at the gym, and the gym instructor said it was abnormal for HR to climb so quickly. He said going up one flight of stairs slowly shouldn't raise it to 120+ so quickly.

I'm on Multaq for AFIB, Bystolic 2.5mg, and Xarelto for past DVT/PE's. I had a recent EKG and Echocardiogram done, and both normal. But it seems like the past few months, my resting heart rate has risen. It used to be 50-60 and now it is 70-80. And when I do any considerable effort, it raises to the triple digits 130+ very quickly.

Also after any sort of activity, my resting heart rate remains elevated at around 100 for a few hours or more. It never comes down, even if i sit down for a few hours. The only time it will come back down, is when i take my Multaq and Bystolic at night.

Should I be concerned or should I believe my cardiologist and EP that everything is fine?

Hey guys, I know it's been awhile since I've posted here, but wanted to revive the discussion a bit. Things were "good" (stable) for awhile, but have been having increase in symptoms despite medication for months now and not sure why. It really strikes me as odd because I quit my stressful job at the end of August and I am not active due to other conditions. I tried walking for awhile, but had to keep stopping because of being short of breath and really lightheaded, etc. The only thing that changed over the last year was my cardiologist switched me from regular Metoprolol to the XL version (still at 25mg tho). Otherwise, I've noticed more and more "black" moments and have to move really slow, or else it feels like I'm going to pass out. My bp and heart rate were actually slow for a time (like around 50bpm and ~90/60; I realize beta blockers lower everything, but this is too low for my "normal"). Now, my resting heart rate is really high again (~125) and the palpitations are really strong/heavy. I don't see my cardiologist until May ... not sure what's going on. Nothing has changed in my life (that I'm aware of) that would cause it to ebb 'n' flow like this. And, I eat pretty cleanly (when I can). Any suggestions or thoughts? I've done my research, but there's always new information as the learning curve keeps growing. Thanks y'all.

@rivermaya34 Wonder if you should be checked with an echo for pulmonary hypertension

@carculmer Not a bad idea, honestly. Thank you for the feedback! I might see if my cardiologist can see me sooner than May; that's still 4 months away.
