Abnormalities of ECG T-wave include T-wave hyperacuity, T-wave inversion, T-wave hypoplasia, etc. The causes may be caused by heart disease such as coronary artery disease, neurosis, and menopausal syndromes.
1. T-wave hyperacuity is mainly seen in the hyperacute stage of acute myocardial infarction, hyperkalemia, and physiological repolarization syndrome.
2. T-wave inversion is mainly seen in coronary heart disease, coronary atherosclerosis, high voltage of left ventricle, and myocardial damage caused by hypertension.
3. T-wave flattening means that the amplitude of T-wave becomes small, which is mainly seen in physiological neurosis, menopausal syndrome and emotional changes; pathological coronary artery disease, electrolyte disorders and myocardial fibrosis.
If T-wave abnormality is found in ECG, further examination and diagnosis should be carried out.
