About A fib and V tach, PVCs and PACs, tachycardia and arrhythmia
Why are A-fib and V-Tach classified under tachycardia arrhythmia while PVC's and PAC's are not under the same category?
A PVC/PAC occurs occasionally, leaving your basic heart rate unchanged. With A fib and V tach your basic heart rate usually changes. The significance of any rhythm abnormality lies in its causes and the effects on your circulation, for instance dizziness and/or fainting.

You’ll find these are rather common complaints and most people don’t need treatment, only reassurance once their heart proves OK. Thus a patient with a new onset of symptoms needs testing, both of the heart rhythm and a variety of blood tests to make sure there is no other heart problem.
Hope this helps,
