tv2＞tv6 is a non-specific electrocardiographic feature, which belongs to the manifestation of early myocardial ischemia. Myocardial ischemia belongs to coronary artery stenosis, caused by insufficient blood supply and oxygen supply to the myocardium, and is mainly manifested by pain in the precordial region, dyspnea, chest pain and other symptoms. Generally, an electrocardiogram (ECG) is often carried out after medical treatment, and the ECG shows that ST-segment elevation, elevated or inverted T-waves, and ECG leads tv2＞tv6, which suggests that myocardial ischemia is extensive at the anterior wall of the myocardium. You can wear a dynamic electrocardiogram to record the condition of the heart under daily activities, showing the time period and duration when ischemia occurs, so as to understand the frequency of myocardial ischemia and its symptoms. Patients with myocardial ischemia should avoid excessive exertion, avoid emotional excitement, abstain from smoking and alcohol, and control the blood pressure and glucose, and if discomfort occurs, they can take nitroglycerin orally to dilate the arteries to alleviate the symptoms. If the patient electrocardiogram suggests tv2>tv6, should promptly consult a doctor, under the guidance of the doctor, to identify the cause of the disease, for treatment.
