Irregular heart rhythms cannot be assessed in terms of severity by the number of episodes; it depends on the specific type of arrhythmia.
Irregular heart rhythms are often indicative of an arrhythmia, and common causes include sinus arrhythmia, atrioventricular block, and atrial fibrillation; for patients with sinus arrhythmia the risk is low, and most patients do not need special treatment, and should have their electrocardiograms reviewed regularly.
Atrioventricular block and atrial fibrillation in patients with the condition of the relative increase in risk, such as repeated episodes can lead to myocardial ischemia, etc., this part of the patient can be long-term survival with the disease, usually does not lead to serious sequelae.
A small number of patients may be severe atrioventricular block, such as second-degree type 2 atrioventricular block, slow atrial fibrillation, atrial fibrillation with extremely fast ventricular rate, the condition is very serious, the patient with the risk of heart failure, myocardial infarction, and even the risk of arterial embolism, a single episode will be at risk, repeated episodes will only lead to a more serious condition.
Patients with arrhythmia should go to the hospital to clarify the specific diagnosis and risk, and give timely treatment under the guidance of the doctor.
