See a Cardiologist: an EKG showing a prolonged QT interval may be associated with a potentially dangerous heart rhythm known Torsades De Pointes. Medications, genetic causes both can be associated with a prolonged QT interval. Concerning historical features also would include a history of fainting or a family history of sudden death. Need more detailed workup with a cardiologist as well as an electrophysiologist

Long QT: The QT interval (and QT corrected for heart rate, QTc) is a measurement from the EKG. Besides a Holter and echo, further investigation may be indicated. Seeing a cardiologist is appropriate and you might look for someone expert in inherited and other causes of long QT. It matters because some of these are associated with risk of arrhythmias. Also look at the lists online of QT-prolonging drugs.
