An ECG heart rate of 103 beats/min is an abnormal heart rate, which is categorized as physiological and pathological and requires active examination and appropriate measures.
Normal heart rate is 60~100 beats/min, less than 60 beats/min is sinus bradycardia, more than 100 beats/min is sinus tachycardia. Physiological causes of rapid heart rate may be after exercise, emotional excitement, drinking coffee and tea, smoking and drinking, usually this situation can be restored with a little relief, no special treatment.
Pathologic causes include hyperthyroidism, hypertension, coronary atherosclerotic heart disease and other causes. It is recommended to do electrocardiogram, blood pressure test, blood routine and blood biochemistry, coronary CT, thyroid function and other tests to clarify the cause of the disease and then give appropriate treatment to bring the heart rate back to normal.
When the heart rate exceeds 100 beats/minute, it is recommended to go to a regular specialized hospital for consultation and treatment under the guidance of a doctor, do not treat it arbitrarily and lightly.
