Whether or not a heartbeat of 110 beats per minute is normal depends on the circumstances. If you have just finished a strenuous exercise, a heartbeat of 110 beats/min is normal. If the heart beats 110 beats per minute at rest, it is considered tachycardic and is abnormal. The number of heartbeats per minute in a normal person in a quiet state is generally 60-100. If you have just done strenuous exercise or your body is in a feverish state, a heartbeat of 110 beats per minute is normal and is a transient tachycardia, which can return to normal after rest or fever reduction. However, if the heartbeat is 110 beats per minute at rest and continues, it is abnormal and may be caused by hyperthyroidism, heart failure or cardiomyopathy. If a heartbeat of 110 beats per minute occurs, rest should be taken. If the heartbeat is not relieved, it is recommended to consult the cardiology department of a regular hospital to check the blood routine, A function, electrocardiogram and cardiac ultrasound to clarify the cause and then treat the symptoms.
