We have observed electrocardiographic (ECG) changes primarily in women during tilt table testing. ⋯ ECG changes during the testing was observed at a relatively high incidence primarily in women. The clinical significance of these repolarization changes during tilt testing is unknown. These ECG changes during tilt testing may correlate with the high incidence of false positive ECGs in women during exercise testing but do not necessarily indicate the presence of ischemic coronary disease. Additional research is needed to explain this phenomenon.
