A heart rate of 38 beats/minute does not determine the presence of heart failure; it is a combination of the patient’s symptoms, cardiac ultrasound, and BNP levels that determine the presence of heart failure. A heartbeat of 38 beats per minute can only indicate the presence of bradycardia, and in some people the presence of bradycardia does not necessarily mean that cardiac insufficiency is occurring. Some patients may not have any symptoms of bradycardia, and in severe cases, they may have symptoms such as fatigue and chest tightness, but they do not necessarily have heart failure. Bradycardia people to determine the existence of heart failure, to understand the patient’s symptoms, such as activity or dyspnea, nocturnal paroxysmal dyspnea, etc., and at the same time for cardiac ultrasound examination, to understand the heart’s ejection function, such as at the same time combined with the BNP level exceeds the normal value, to be considered with the possibility of heart failure. Early consultation is recommended to avoid delaying the condition.
