tests back from PVC runs.....confused please respond

So I had all the tests because after a year or so my PVC's flared up again and are reeking havoc an my anxiety.  I have no insurance as I am a college student (will be an RN in May yeah!) so I was lucky to get this much done at the free clinic down town, I don't think they will run anymore.  So the holtor is as followa (of course I had no runs or symptoms while wearing the monitor..par for the course) " There are 133,215 QRS complexes with a minimum HR of 60bpm, average of 93BPM, and 168 BPM maximum rate.  There are no significant ventricular events or supraventricular events.  Clinical correlation is needed."  So what is clinical correlation mean?  My doctor rushed to put me on beta blockers after reading this..saying my heart is flunctuating to much and going to high...but I aerobically excercised for 45 minutes...shouldn't my heart have gone up to 168?  She is a nurse practitioner and I am wondering if she knows anything about this.
MY ecg read" normal sinus rhythm with sinus arrhythmia.  NORMAL ECG."
Now my echo is long so I will just say it says " Normal  left ventricular systolic function.    All valves are morphologicall normal.  Ejection fraction is between 55%-60%.  Atria and ventricals all withion normal limits.  Mild mitral regurgitation noted.  Mild tricuspid regurgitation seen.  Trace pulmonic insufficiency noted on color doppler."
SO what do you all think, structurly normal?  Whats the regurg and insuffiency?  Why on beta blockers if not being given for PVC sysmptoms?  I just need advice.  I can't afford a cardiologist.

It doesn't sound like you had any PVCs on this test. QRS complexes are just heartbeats, as far as I know.  Seems like you had 133,215 of them during the whole test.  Sinus arrhythmia is normal, I have it too (very pronounced).  It accounts for a lot of my symptoms when I think I"m having palpitations - it is just sinus arrhythmia.  Sounds like she wanted to put you on betas because of high HR, who knows why?  Maybe she didn't realize you had exercised when you were wearing the holter.  Maybe you can tell her you were and she will not see the need for betas.  Overall, these results seem good.  I have trivial regurge in tricuspid and mitral valves, too, and my doc said it's still a "normal heart."

Let's see...133,215 QRS complexes...beats?  If this was a 24-hr Holter monitor, then that's about 92 bpm on average...a little high, so maybe that's the reason for a beta blocker.  Sounds pretty normal to me, especially if you were exercising.  -Arthur

92 BPM is not a high average for someone exercising 45 mins per day. Resting heart rates are normal between 60 and 100 BPM, but rise much higher during daily activity. I suggest seeing a real Doctor. You should not be on a Beta blocker unless absolutely necessary. They have some side effects.

Don't stop taking the Beta Blockers until you see your Doctor, as there may be some factors we're not aware of.
