Partial lead ST-T changes on ECG refers to abnormal changes in ST segment and T wave on ECG, which need to be comprehensively judged based on symptoms, signs and auxiliary examinations.
ST-T changes in partial leads of ECG include ST segment elevation or depression, T wave hyperacuity, hypoplasia, bi-directionality or inversion, and other abnormal changes of ST segment and T wave, which represent ventricular repolarization abnormality. The causes of ST-T changes include cardiac factors such as coronary artery disease, myocarditis, arrhythmia, etc., and non-cardiac factors such as electrolyte disorders and drug effects such as digitalis.
When ST-T changes appear in ECG, it is necessary to combine with one’s own symptoms and signs to make a comprehensive assessment. When clinical symptoms such as frequent chest tightness, chest pain, palpitations, etc. appear, it is necessary to consult a doctor in time, and improve the dynamic electrocardiogram, myocardial enzymes, cardiac ultrasound, coronary angiography and other related laboratory tests and examinations to make a comprehensive diagnosis, and active treatment.
