When the cardiac ultrasound of st segment change is not a problem, the transient change of st segment usually does not need treatment, and the long-term, bow-back upward of st segment or combined with the progressive change of ECG needs treatment.
1. If the cardiac ultrasound indicates that there is no problem and the ECG shows a transient depression of the st-segment, displacement, inversion of the t-wave, etc., which can be caused by temporary myocardial ischemia and can be recovered after a short rest, there is no need to worry about it, and no treatment is needed in general.
2. Although the heart ultrasound suggests that there is no problem, but the electrocardiogram shows long-term changes in the st segment, which may suggest that the cardiomyocytes are in a long-term ischemic state, the onset of the attack should be rested immediately, depending on the circumstances of the nitrate drugs, such as nitroglycerin, nitrate isosorbide, etc., and those who continue to have difficulty in relieving the problem should be coronary arteriography and other related auxiliary examinations for systematic diagnosis and treatment.
3. Although the heart ultrasound suggests that there is no problem, but the electrocardiogram st segment shows multi-lead bow-back upward elevation, there may be myocardial infarction, should be immediately sublingual nitrate drugs, at the same time, immediate emergency medical care, through thrombolysis, interventional surgery to restore myocardial perfusion.
4. Although the heart ultrasound suggests that there is no problem, but the electrocardiogram st-segment changes combined with electrocardiogram progressive changes, such as the emergence of wide and deep Q-wave, T-wave persistent inversion, accompanied by difficult to alleviate chest pain, is also highly suggestive of possible myocardial infarction, should be immediately sublingual nitrate drugs, and at the same time, immediate emergency medical treatment, through thrombolysis, interventional surgery to restore myocardial perfusion.
If there is no problem with the ultrasound of the heart, the change of the st-segment may also indicate multiple heart problems, and those who have difficulty in relieving the problem through the above methods should consult a doctor as soon as possible for systematic diagnosis and treatment.
