When is accelerated idioventricular rhythm considered frequent? i've been have an episode once a month for the past 3 months?

I would consider this frequent as it should not be happening. YOUR BODY IS TALKING TO YOU! Listen & take good notes. When does it start/stop? Where does it go? What makes it better/worse? How long does it last? Medication helps/worsens? 
If you think it is something you eat/drink/do stop it & see. If better, go back again & retest until u r convinced it is something u should stop. Then stop
