First-degree AV block can worsen and progress to second or even third degree.
First-degree AV block is an incomplete atrioventricular block with a time delay in the transmission from the atria to the ventricles. Typically, patients often have no noticeable self-symptoms and usually do not require treatment. If AV block is caused by other primary diseases, the primary disease should be actively treated.
However, patients should be aware that patients with first degree AV block need to be examined regularly, as it can progress to second or even third degree, with discomfort such as chest tightness and panic attacks.
Therefore, people with atrioventricular block, a history of heart disease, and a history of heart surgery are advised to have regular checkups to avoid delays.
