Is heart rate above 120 heart failure?

Heart failure is a group of syndromes caused by abnormal cardiac structure or function, resulting in impaired ventricular filling or ejection function. The main manifestations are dyspnea, fatigue, edema, etc., but these symptoms are not specific and may also be caused by other causes. Increased heart rate can be one of the manifestations of heart failure, but other conditions may also lead to increased heart rate, such as strenuous exercise, emotional excitement, fever, anemia, hyperthyroidism, etc. In addition, some heart diseases, such as arrhythmia, myocarditis, pericarditis, etc., may also cause heart rate to increase. To determine whether heart failure exists, clinical manifestations, physical examination, laboratory tests, and cardiac imaging should be considered. The doctor will ask for a detailed medical history, perform a physical examination, evaluate the structure and function of the heart, and may perform ECG, echocardiography, cardiac MRI, etc. to confirm the diagnosis. For cases where the heart rate has been above 120 beats/min, it is recommended to seek medical attention in time for a comprehensive evaluation and diagnosis. The doctor will formulate the appropriate treatment plan according to the specific situation, which may include lifestyle adjustment, drug treatment, cardiac rehabilitation, etc. For high-risk people with cardiovascular disease, hypertension, diabetes, etc., regular physical examination should be carried out to pay attention to changes in heart function. If there are symptoms such as palpitations, dyspnea, fatigue, etc., timely medical treatment should be sought for early detection and treatment of heart disease. In short, heart rate has been more than 120 beats/min is not necessarily heart failure, but it needs attention. Timely medical treatment, comprehensive evaluation and diagnosis, in order to take appropriate treatment measures to protect heart health.
