Introduction
Whether flat T waves in leads V4–V5 under sinus rhythm are considered serious depends on the clinical context and cannot be generalized. If no physical discomfort is present, it is usually not considered severe. Adequate rest should be emphasized in daily life, along with regular use of lipid-lowering and antihypertensive medications. However, if these changes occur frequently and cause symptoms such as chest tightness or chest pain, the condition may be relatively serious.
Sinus rhythm with flattened T waves in leads V4–V5 may or may not indicate a serious condition; the severity depends on individual circumstances and cannot be generalized.
1. Not serious: During testing, flattened T waves in leads V4–V5 typically suggest mild myocardial ischemia. If no physical discomfort is present, the condition is generally not considered serious. It is important to ensure adequate rest and consistently take prescribed medications for lowering blood lipids and controlling blood pressure.
2. Serious: If flattened T waves in leads V4–V5 occur frequently and are accompanied by symptoms such as chest tightness, chest pain, or palpitations, the condition may be more serious, possibly indicating diseases such as myocarditis or coronary artery atherosclerotic heart disease. Timely treatment targeting the underlying cause is necessary to avoid delaying diagnosis and preventing harm to health.
Electrocardiogram (ECG) findings alone cannot provide an accurate diagnosis. It is recommended to promptly visit a hospital for further evaluation, such as coronary angiography or other CT imaging tests, to determine the exact condition.
