Abnormal EKG

Im 37+4 high risk scheduled for induction in 9 days at 39 weeks and had what they told me was a standard EKG last week. Today they called and said I need a cardiologist because it came back 'abnormal' they can't give me any more information at this time. Has anyone else has an abnormal EKG? I have an appointment on January 18th for more tests but I'm just wondering about others experiences.
