Hello, there are many causes of an elevated heart rate. Common ones include fever—since an increase in body temperature can accelerate the heart rate—as well as intense physical activity or emotional fluctuations. Cardiac conditions, such as congenital heart disease or arrhythmias, may also lead to tachycardia. We recommend visiting the Department of Cardiovascular Medicine at a hospital. Based on your symptoms, the physician will arrange appropriate diagnostic tests to establish a definitive diagnosis and initiate targeted treatment. I hope this information is helpful. Wishing you good health!
