Nocturnal episodic second-degree type 1 AV block usually does not require treatment if there are no other symptoms, but it must be observed regularly, and if it is accompanied by other symptoms, it needs to be treated aggressively. 1. Asymptomatic second-degree type 1 AV block: the block is located in the atrioventricular node, no treatment is needed at this time, only regular follow-up observation; when the block area of second-degree type 1 AV block is located in the Hippocampus system, it is necessary to actively treat the primary pathology, symptomatic treatment, and to consider the application of cardiac pacemakers. 2. Symptomatic second-degree type 1 atrioventricular block, especially with a history of syncope: no matter where the block is located, active treatment is needed, which can be done by oral or subcutaneous injection of atropine, or the use of isoproterenol or aminophylline. 3. Acute myocardial infarction with second-degree type 1 AV block: it occurs in patients with inferior wall infarction and usually does not require treatment. For those with heart rate slowing, atropine can be given orally or subcutaneously, or aminophylline tablets can be given orally. Nocturnal episodic second degree type 1 AV block is not a cause for concern and should be followed up or treated as prescribed by the physician.
