In adults, the resting heart rate is lower than 60 beats/min (usually above 45 beats/min), it called sinus bradycardia, which can be seen in healthy people and athletes who have been engaged in heavy physical labor for a long time ,or it be seen in hypothyroidism, intracranial pressure Increased height, obstructive jaundice, and overdose of digitalis, quinidine, or propranolol. It should be considered sick sinus syndrome and atrioventricular block, if the heart rate is lower than 40 beats/min.Atrial fibrillation should be considered if the pulse is unequal, irregular, and less than the heart rate.
Many people will have sinus bradycardia with arrhythmia, which is normal for most people and should not be overly concerned. Sinus bradycardia refers to people whose heart rate is less than 60 beats per minute, whether or not this symptom occurs is related to the frequency of the bradycardia and the cause of the bradycardia. In a quiet state, if the heart rate of an adult is between 50 and 60 beats per minute, there will generally be no obvious symptoms. Especially some well-trained athletes and people who have been engaged in physical work for a long time will not have obvious symptoms even if their heart rate is around 40 beats per minute in a quiet state. However, if the heart rate of an average person is between 40 and 50 beats/min, symptoms such as chest tightness, fatigue, and dizziness will appear, the blood supply is affected, resulting in chest pain, dizziness, syncope and even sudden death. If you don’t feel any discomfort, don’t pay attention to the “sinus bradycardia with arrhythmia” mentioned by the electrocardiogram, but if you have symptoms such as chest tightness, fatigue, dizziness, etc., you should immediately go to the hospital for further examination, such as dynamic electrocardiogram, cardiac color Doppler ultrasound If the heart beats slowly, you can relieve symptoms and improve prognosis by installing a pacemaker.
