A pulse rate of 110 beats/min is abnormal. A normal human heart rate is 60-100 beats/min, <60 beats/min is bradycardia and >100 beats/min is tachycardia. A normal heartbeat starts at the sinus node, and a heart rate of 60-100 beats/min is called sinus rhythm, and >100 beats/min is called sinus tachycardia. A quiet state with <100 beats/min is normal. If the rate exceeds 100 beats/min in the quiet state and reaches 110 beats/min, it is called tachycardia. Tachycardia is a symptom and a manifestation of a number of diseases that cause tachycardia. The most common are anemia, infection, fever after infection, and a faster heart rate in patients with fever. There is also hyperthyroidism, which can cause tachycardia. If your heart rate is 110 beats per minute faster in a quiet state, you should go to the hospital for further examination to find the cause. It is normal to have a heart rate of more than 110 beats/min after exercise, and this can be relieved after rest.
