Whether or not a pulse of 45 to 50 beats/minute requires treatment requires an assessment of the severity of the condition; if bradycardia is accompanied by symptoms such as chest tightness, fatigue, and dizziness, treatment to increase the heart rate needs to be given. A pulse rate of 45~50 beats/minute requires knowledge of the patient’s state at the time the heart rate is detected. If this heart rate occurs during sleep, not much treatment is needed. Bradycardia in the waking state, if accompanied by related symptoms, such as chest tightness, fatigue, dizziness, etc., need to be given to raise the heart rate of the drug treatment, for example, you can take oral atropine, cardiopulmonary pills and other drugs. For patients with bradycardia, a 24-hour ambulatory electrocardiogram is recommended. To find out whether the patient is in sinus rhythm, with or without long intervals, atrioventricular block, for bradycardia with obvious symptoms, if necessary, need to install pacemaker treatment. Patients with bradycardia should be evaluated under the guidance of a physician to decide on a specific treatment plan.
