A heartbeat consistently above 100 beats/min may be an abnormality, and to avoid adverse consequences, it is recommended to visit a hospital cardiology department for an examination. The heart rate of a normal adult should not exceed 100 beats/min, and more than 100 beats/min can be called sinus tachycardia. Some patients may have a heart rate exceeding 100 beats/min due to emotional excitement, work stress, anxiety, drinking tea or coffee, etc., which may lead to a faster heart rate. In addition, pathological causes such as hyperthyroidism and anemia can also lead to sinus tachycardia. Because the heart has a certain compensatory capacity, it can still maintain normal life operation even if the heart rate exceeds 100 beats per minute. However, if the heart rate is consistently too fast, it may cause ventricular fibrillation, atrial fibrillation, heart failure, and heart enlargement, which require attention. Patients whose heart rate is always above 100 beats/min are advised to visit the cardiology department of the hospital in time to find the cause of the problem.
