In brief: Partially yes
The most common irregular heart beat is sinus arrhythmia which is a respiratory variation in the regularity, a perfectly normal heart rhythm and not indicative of any disease.
The most common abnormal heart irregularity is atrial fibrillation, with some 2-3 million people having this heart rhythm.

In brief: Depends
It depends in what time of person the irregular heart beat is happening.
Someone young may be more likely to have premature atrial or ventricular contractions (pacs or pvcs) than af.
