It doesn’t matter if you have atrioventricular block, the patient is usually asymptomatic, and it usually doesn’t require any special treatment. Atrioventricular block mainly refers to the delayed conduction of impulses from the atria or the inability to conduct to the ventricles, resulting in arrhythmia. The grading is based on the severity of the block, and in first-degree block, the conduction time is prolonged, but all impulses are still able to be transmitted, which is usually characterized by the progressive prolongation of the conduction time until one impulse is not able to be conducted. Because first-degree AV block is generally mild and common, patients are usually asymptomatic and no specific treatment is usually required. If symptoms of cardiac discomfort occur, it is necessary to go to the hospital as soon as possible, and the doctor will formulate individualized treatment plans according to the specific conditions, so as to avoid delays in the condition.
