Examination of the heart for second-degree type 1 AV block begins with an electrocardiogram (ECG), to which dynamic ECG monitoring and cardiac ultrasound can be added.
Second-degree type 1 AV block is a type of arrhythmia that can be shown by routine ECG, and ECG is relatively simple and easy to perform and non-invasive, making it an essential test for clinical diagnosis of arrhythmia.
Sometimes an arrhythmia may not be revealed or identified by several routine ECG examinations. Ambulatory ECG monitoring is a continuous 24-hour tracking record, which can provide a comprehensive and powerful basis for confirming the diagnosis of arrhythmia.
Both physiologic and pathologic cardiac factors are present in second-degree type 1 AV block. Pathologic factors such as congenital cardiovascular disease, aortic valve stenosis with calcification, and cardiac tumors may cause it, and cardiac ultrasound allows for a better assessment of cardiac function.
When second-degree type 1 AV block occurs, it is important to go to the hospital in time to be diagnosed and treated by a specialist and followed up, and not to delay the condition or treat it arbitrarily without authorization.
