How long a 30 year old can live with conduction block usually takes into account the type of conduction block the patient has, and is treated with aggressive interventions that have little impact on survival. When the patient has one degree of AV block, the AV conduction time is prolonged, but the atrial palpitations can still be transmitted to the ventricle, mostly in normal people or athletes and myocardial infarction and other cardiac diseases, this occurs for asymptomatic need not be dealt with, the main focus on the treatment of the primary disease. When second-degree AV block occurs, usually in the atrium to the ventricle process, there will be part of the conduction interruption, the phenomenon of ventricular leakage can occur as well as delayed atrioventricular block, not only will lead to circulatory disorders, the serious cases can be transient loss of consciousness, can be through the doctor’s orders orally or subcutaneously injected atropine and so on. When third-degree AV block occurs, patients may experience palpitations and dizziness, mainly due to abnormalities in the atrioventricular conduction system, resulting in complete atrioventricular segregation phenomenon, and in severe cases, there may be a loss of consciousness and other conditions. Atrioventricular block, once diagnosed with the disease, requires active treatment and intervention under the guidance of a doctor in order not to affect the patient’s survival cycle, and in most cases the recovery is good.
