The heart rate range for adult women is 60-100 beats per minute. If it is less than 60 beats per minute, it is called bradycardia. If it is greater than 100 beats per minute, it is called tachycardia. For athletes and people who do physical work for a long time, the heart rate can be slightly slower, around 50-60 beats per minute. If the heart rate is consistently below 50 beats per minute, it is called significant bradycardia, and the cause of the bradycardia should be sought, such as hypothyroidism, acid-base electrolyte disorder, myocarditis, acute myocardial infarction, etc.
