St segment refers to what area of waveform
WebApr 4, 2002 · Initially the ST segment may straighten, with loss of the ST-T wave angle . Then the T wave becomes broad and the ST segment elevates, losing its normal concavity. As further elevation occurs, the ST segment tends to become convex upwards. The degree of ST segment elevation varies between subtle changes of <1 mm to gross elevation of … WebDec 8, 2024 · Nonspecific ST-T-wave changes are very common and may be seen in any lead of the electrocardiogram.
