Normal blood pressure, abnormal pulse.
Normal blood pressure values are 90-139/60-89mmHg and normal pulse is 60-100 beats per minute. Thus blood pressure 91/65 mmHg is normal and pulse rate 57 is below the normal range.
Low pulse may be caused by physiological bradycardia, such as slowing down of metabolism in most of the old people, which can make the heart rate and pulse low; long-term heavy laborers, athletes and other cardiac contractility, cardiac output increases, so that the heart rate slows down compensatory, and the pulse is low.
Low pulse may also be caused by pathologic bradycardia, such as atrioventricular block can affect the normal pacing function of the sinus node, resulting in bradycardia, low pulse; hypothyroidism, cachexia and other patients with their own metabolism slows down, resulting in a slow heart rate, lower pulse.
If the factors of physiological bradycardia are excluded, and the pulse rate is still lower than normal for a long time, it is recommended to go to the regular hospital in time, to clarify the cause of the disease, and to carry out standardized treatment under the guidance of the doctor.
