Sinus bradycardia with arrhythmia is an indication that the patient’s heart rate is lower than normal and there is an arrhythmia, which should be treated under the supervision of a medical professional if necessary. Sinus bradycardia with arrhythmia is a term commonly used in electrocardiograms to indicate the presence of sinus bradycardia with arrhythmia in the patient’s heart. Normally, the human heart begins to beat in the sinus node, so a normally paced heart is in sinus rhythm. Adults in a quiet state heart rate of 60 to 100 times / min between, when the heart rate is lower than 60 times / min, that is, sinus bradycardia; normal human heart rhythm is regular, when the heart rhythm appears irregular performance, that is, arrhythmia. Sinus bradycardia with arrhythmia can be seen in physiological situations. For example, athletes or physically fit people may experience sinus bradycardia with arrhythmia without specific clinical symptoms and generally without intervention. Sinus bradycardia with asymmetry can also be seen in some pathological conditions, such as patients with improper use of drugs, sinus node function abnormalities, atrioventricular block, etc., which can lead to a decline in the ejection function of the heart, the systemic blood supply to the system to reduce the appearance of palpitations, dizziness, chest tightness performance, the serious cases can be life-threatening, the need for timely treatment. Therefore, when the patient has sinus bradycardia with irregularities, he should consult a doctor in time to clarify the cause of the disease, and if necessary, under the guidance of a professional physician, timely treatment, so as not to lead to adverse consequences.
