   15 Νοε 2023 · Patients with third degree heart block are at high risk of ventricular standstill and sudden cardiac death. They require urgent admission for cardiac monitoring, backup temporary pacing and usually insertion of a permanent pacemaker. Differential diagnosis.

   Third-degree atrioventricular (AV) block (also referred to as complete heart block) is the complete dissociation of the atria and the ventricles. 1 Third-degree AV block exists when more P waves than QRS complexes exist and no relationship (no conduction) exists between them. 2 The escape rhythm may arise within the AV node (resulting in a narrow QRS complex), or lower in the conduction system ...
