Abnormal Heart Rhythm

Has anyone experienced abnormal heart rhythm with their GBS? I have been checking my blood pressure and heart rate which have been normal but at times my heart rhythm feels off. It happens in my sleep and sometimes after I'm awake. I experienced this back in June 2014 when this first happened but now am finding it happening again with this re-flare of symptoms. It happens so sporadically and doesn't last long. It's so inconsistent. I have had more twitching at times in my chest and abdominal area. I'm not nervous about it so I don't feel that this is an anxiety issue. It's really something that happens on its own not when I'm trying to work or workout. Over the last couple of days,I have noticed more muscle twitching and inner nerve shaking. Is this something that corrects itself with time? Or has anyone had to see a cardiologist?
