Proposed a new method for detection of ischemia using mathematical isoelectric energy function.

The proposed method does not involve any training and complicated calculation.

Detection of ischemia class for detected ischemic episode.

Achieved 98.12% average sensitivity and 98.16% average specificity.

The results are significantly better than those of existing methods for recordings of European ST-T database.

The advantage of the proposed method includes the automatic discarding of noisy beats.
