I've never heard of "normal sinus rhythm arrhythmia".  Perhaps the words ran together, I'm guessing it should say "sinus arrhythmia".  It's perfectly normal.   Everyone has it to some degree.  There is plenty of info on the 'net about this already, Google "sinus arrhythmia".    I will add that SA makes gas exchange in your lungs more efficient, nature evolved it for a reason.  When you inhale your heart will speed up a bit, getting more blood into your lungs to release CO2 and absorb O2.  When you exhale the heart slows down.  You autonomic nervous system (ANS) controls this activity through the sinus node.  Because the heart speeds up and slows down it's called an arrhythmia.  See, not all arrhythmias are bad.

I personally feel that folks with a stronger sinus arrhythmia have youthful ANS activity along with a well functioning heart.  Be grateful you have it.  When you get older it will degrade.

Hi  r9c,

Yes, PVCs will show up on an EKG.  They are such a bizarre wave form that they stand out like sore thumbs.
