First-degree AV block needs to be reviewed once every 3 to 6 months.
First-degree AV block is a condition in which atrial conduction is prolonged beyond the normal range, but each atrial excitation is transmitted to the ventricles. There are many causes of atrioventricular block, such as myocardial ischemia, myocardial infarction, myocarditis, degenerative heart disease in the elderly, as well as some medications that can cause atrioventricular block, such as digitalis, calcium channel blockers, and beta-blockers.
Generally, asymptomatic atrioventricular block does not require treatment, but it is necessary to continue to monitor whether it progresses to severe atrioventricular block or serious arrhythmia, etc., and follow the doctor’s instructions to measure the pulse and review regularly.
If the patient develops symptoms such as dizziness, panic, shortness of breath, etc., it is important to pay close attention to the patient and consult a doctor promptly.
