Whether ECG conduction block from childhood grows up and returns to normal is determined by the type of conduction block and the specific condition. For people who grow up with heart conduction block without any symptoms or organic heart disease, it usually does not affect their health and does not require treatment. ECG conduction block can have the following conditions 1. First degree AV block: seen in normal people, with age may return to normal ECG, regular review is recommended. 2. Second-degree atrioventricular block: There are two types of atrioventricular block, second-degree type I and second-degree type II. Second-degree type I block may recover after treatment. Second-degree type I block may recover with treatment. Second-degree type II block is a high degree of conduction block, and recovery is generally unlikely. 3. Third-degree AV block: Third-degree AV block does not respond well to medication and requires pacemaker placement. Therefore, for ECG conduction block, we need to find out the cause, and if there is organic heart disease, we need to take medication under the guidance of specialized doctors, and install a pacemaker if necessary.
