skip beats/arrythmias

i still get skip beats and i just started taking 10 days ago antenlol 12.5mg a day.  still have same problem but it lessened its not a terrible feeling when i got them they were pretty intense before the medicine now they calmed down but still get them.  its not a miracle pill, which worries me, because will i always have this? will it ever go away? i wonder if that ep study really works? my doctor is thinking about doing it on me.  they say its a 80% success rate but i might be that 20% that doesnt! make it. will there ever be a cure for this?
