Changes in the progression of ST segments provide the medical expert with important diagnostic information. In the resting ECG, the ST segment indicates acute or infarction events that occurred long before. In the stress ECG, ST segment changes can be suggestive of ischemia, which means shortages in the supply of the heart. Here we have to consider that a reliable evaluation must be exclusively in the hands of a medical expert, as the J point is situated on the height of the isoelectric line in resting state. With stress however, the J point is lowered physiologically and originating from this point ascending ST segments will develop. A characteristic sign of a clearly stress-dependent ischemia is the ST depression in the left-precordial chest leads. custo diagnostic thus offers multiple option of identifying ST segment deviations and of quantifying their scope. It consequently makes an important contribution to diagnosis and therapy.
