Thank you for taking the time to look at and answer all of our questions.
I was having bronchitis on 10/6/18 and while driving my car I felt my heart rate extremely elevated (a hot flush went through my body before that). I pulled my car and went to the nearest pharmacy where my bp and bpm were measure with a BP machine. My heart rate was 178 bpm at rest and my BP was somewhere around 140 over 90.
I rushed to the nearest ER but until I got there my heart rate was back and settled to around 100 bpm and they could not catch anything apart from sinus tachycardia.
Since then, I've experienced same episodes around 5-6 times, where my HR at rest was peaking between 165-175 bpm. I could never catch it on an ECG.
I've had numerous ECGs done, 2 echos (trivial MPV with mild regurgitation & tricuspid mild valve regurgitation, but they say that's structurally normal heart and the findings are trivial).
I also had a stress test, which came back normal with a few PVCs during the test and during recovery.
I've had 3 different holter monitors all of them coming back normal with the exception of acceptable amount of PVCs (as the doctors said).
However, my last Holter monitor caught an episode of monomorphic wide complex ventricular tachycardia - 3 beats at 160 bpm, lasting 1 second. I've also seen an EP for that who told me to just forget about it, which is really hard for me to do.
One more thing is that my HR drastically changes upon standing. It can be 80 sitting and as soon as I stand up it increases to 120-130 bpm and stays there. Even the slightest movement increases my HR drastically. I've been advised to exercise but I cannot imagine doing that, since my HR is 130 bpm just standing.
I am reaching out to see what might me your opinion as I am clueless as of what to do next.
