Core Tip: This report introduces a case of complete atrioventricular block caused by atrial septal defect occluder. During the placement of the occluder, a complete atrioventricular block suddenly appeared. Electrocardiograph monitoring showed that the ST interval in the inferior wall lead was prolonged, P wave and QRS complex were separated, the heart rate was maintained by junctional escape rhythm, and the blood pressure began to decrease.
