The heart rate of 55-60 beats/minute is not enough to determine whether it is heart failure or not, but should be combined with medical history and other auxiliary examinations. If the heart rate is less than 60 beats/minute, it belongs to bradycardia, which can be seen in pathological as well as normal people. If there is no clinical symptom, there is no need for special treatment, and if necessary, follow the doctor’s instructions to improve the thyroid function, electrocardiogram and other related examinations. The heart rate of patients with heart failure can be increased or decreased, so it can not be judged only by the heart rate. To determine the presence of heart failure, it is necessary to take into account the medical history, symptoms and other ancillary tests. These patients usually have underlying heart disease and symptoms such as dyspnea, chest tightness, lower extremity edema, etc., and need to be diagnosed in combination with BNP, cardiac ultrasound and other auxiliary examination results. If the heart rate is only 55~60 beats/minute, there is no need to be overly nervous, and if necessary, go into a hospital for consultation to clarify the diagnosis.
