WebNov 20, 2024 · Third-Degree Atrioventricular Block. A complete failure of the AV node to conduct any impulses from the atria to the ventricles is the main feature of third-degree atrioventricular block. There is AV dissociation and escape rhythms that may be junctional or ventricular, which represent perfusing rhythms. WebThird-degree heart block means that no impulses are reaching the ventricles. To make up for this, the ventricles use their own “backup” pacemaker with its slower rate. Because a gap in time is likely to occur between the impulse from the atria and the impulse from the “backup” pacemaker in the ventricles, a person may faint.
