Abstract

The results of study on T-wave alternans in the group of patients with ischemic heart disease are shown. The body surface potential maps were recorded with use of 67 channel high-resolution ECG system. Electrocardiographic stress test was performed during the patient examinations. The T-wave alternans ratio was calculated and results were compared with data obtained by single-photon emission computed tomography (SPECT). Significant correlations between results of T-wave alternans analysis and SPECT test have been found.
