The term ST-T changes is commonly used in clinical practice to refer to changes occurring on the ST-T segment (from the J point to the end of the T-wave). Ischemic ST-T changes Ischemia affects the plateau phase (phase 2) and the rapid repolarization phase (phase 3), which is why ischemia causes changes to the ST segment and T-wave (ST-T changes). A: ST segment and T wave are ECG terminologies and these are arbitrary names given to certain segments of the tracings of the ECG. ST-T wave changes can occur in a number of situations, which are Basic Concept: the specificity of ST-T and U wave abnormalities is provided more by the clinical circumstances in which the ECG changes are found than by the particular changes themselves. Thus the term, nonspecific ST-T wave abnormalities, is frequently used when the clinical data are not available to correlate with the ECG findings. Non-specific ST-T wave abnormalities can be caused by digitalis effect, myocardial ischemia, hypokalemia, left ventricular hypertrophy with strain and reciprocal changes from an ST elevation myocardial injury. Getting an electrocardiograph test will help diagnose the problem.

The differential diagnosis of ST-segment depressions includes acute coronary syndrome (non-STEMI or unstable angina), ST-segment depressions that are reciprocal to a less-obvious STEMI, pulmonary embolism, left ventricular hypertrophy with repolarization abnormalities (strain pattern), digitalis effect, various cardiomyopathies, electrolyte disturbances and other miscellaneous conditions. 2010-06-14
Electrophysiology. The ST segment starts from the J point (termination of QRS complex and the beginning of ST segment) and ends with the T wave.The ST segment is the plateau phase, in which the majority of the myocardial cells had gone through depolarization but not repolarization.The ST segment is the isoelectric line because there is no voltage difference across cardiac muscle cell membrane
