On few egcs showed st elevation and early repolarization - im suffering from chest pain over a month- last troponin was ok- what's the cause?

ECG : St elevation can be from benign early repolarization, pericarditis, and acute cardiac problems. You list cardiac cath, if that is normal then early repolarization in you would likely be benign.

Find a MCG test!: Here is the link! http://en.M.Wikipedia.Org/wiki/multifunction_cardiogram other causes may be sought!
