An electrocardiogram showing a flattened t-wave v4v5 often suggests myocardial ischemia in the anterior lateral wall. 1.T-wave flattening mainly suggests myocardial ischemia, and the degree of T-wave flattening is proportional to the degree of ischemia. If there is no chest tightness and chest pain, you need to keep enough sleep, you can exercise properly, and review the ECG regularly. In patients with coronary artery disease, ECG may cause persistent T-wave flattening and ST changes. 2. V4 and V5 leads usually indicate the range of the anterior interstitial wall of the heart, so low T wave in V4 and V5 leads usually shows myocardial ischemia in the anterior interstitial wall. T-wave flattening in leads V4 and V5 requires further examination to determine the cause of the disease and prompt treatment.
