Samsung Health-Heart Rate-Measurement, put your fingertips on the heart rate sensor on the back of the device for measurement.
Heart rate refers to the number of heartbeats per minute of normal people in a quiet state, also known as quiet heart rate, which is generally 60 ~ 100 beats per minute, and may vary among individuals due to age, gender or other physiological factors. Generally speaking, the younger the age, the faster the heart rate, the slower the heart rate of the elderly than the young, and the faster the heart rate of women than men of the same age. These are normal physiological phenomena. In a quiet state, the normal heart rate of adults is 60 ~ 100 beats/min, and the ideal heart rate should be 55 ~ 70 beats/min (the heart rate of athletes is slower than that of ordinary adults, generally about 50 beats/min).
When adults are at rest, the heart rate exceeds 100 beats/min (generally not more than 160 beats/min), which is called sinus tachycardia. It is common after excitement, excitement, smoking, drinking or drinking strong tea or coffee, or under pathological conditions such as infection, fever, shock, anemia, hypoxia, hyperthyroidism, heart failure, or when atropine is used.
When the adult's heart rate is lower than 60 beats/min (generally more than 45 beats/min), it is called sinus bradycardia, which can be seen in healthy people and athletes who have been engaged in heavy physical labor for a long time; Or in hypothyroidism, intracranial hypertension, obstructive jaundice and excessive digitalis, quinidine or propranolol. Sick sinus syndrome and atrioventricular block should be considered if the heart rate is lower than 40 beats/min. If the pulse intensity is uneven and the pulse rate is less than the heart rate, atrial fibrillation should be considered.
