Introduction
In general, third-degree atrioventricular block, also known as complete atrioventricular block, is a serious type of arrhythmia. Whether complete atrioventricular block can resolve spontaneously depends on the underlying cause. If it is caused by reversible factors, spontaneous recovery is generally possible. However, if it results from irreversible causes, these pathological changes are often permanent and cannot be reversed.
In general, third-degree atrioventricular block, also known as complete atrioventricular block, is a serious type of arrhythmia. Whether complete atrioventricular block can resolve spontaneously depends on the underlying cause. If it is caused by reversible factors, spontaneous recovery is possible. However, if it results from irreversible causes, these conditions are often permanent and cannot be reversed.
If complete atrioventricular block is due to reversible causes—such as digitalis toxicity, myocarditis, acute myocardial infarction, or hypothyroidism—it may resolve spontaneously following effective treatment of the primary condition and removal of the causative factor. In such cases, cardiac conduction function gradually improves as the underlying disease resolves.
However, when complete atrioventricular block arises from irreversible causes—such as severe intrinsic damage to the cardiac conduction system or significant coronary artery stenosis or occlusion—the pathological changes are typically irreversible, making spontaneous recovery unlikely.
Patients are advised to follow a diet that is low in salt, low in fat, light, and easily digestible in daily life. They should avoid extreme hunger or overeating, opt for smaller, more frequent meals, and thereby reduce the burden on the heart. At the same time, maintaining balanced nutrition helps enhance overall immunity and physical resilience.
