T-wave changes alone are not dangerous, but they are dangerous if they are caused by myocardial ischemia.
1. T-wave changes are common ECG changes. Some young people, especially young women, may experience low T-wave flattening during an ECG examination. If there is no obvious physical discomfort, this condition is not dangerous.
2. If the T-wave changes are caused by myocardial ischemia, such as T-wave inversion, then it is still dangerous. Especially if the patient has a heart attack, he must receive treatment as soon as possible, otherwise there will be a certain risk, even life-threatening.
It is recommended that the patient can do further examination under the guidance of the doctor, such as coronary angiography and other tests, to clarify whether the T-wave changes are pathologic. If it is clear that the T-wave changes are pathologic, it is necessary to pay attention and follow the doctor’s instructions for appropriate treatment.
