third degree atrioventricular block
- third degree atrioventricular block
- a third degree heart block due to total cessation of impulse conduction through the atrioventricular junctional tissue; no correspondence exists between atrial and ventricular activity, and ventricular asystole and death occur unless a ventricular pacemaker is activated.
Congenital complete third degree atrioventricular (AV) block. No P wave is followed by a His bundle potential, whereas each ventricular depolarization is preceded by a His bundle potential. HBE, His bundle electrogram; RA, right atrium; RV,right ventricle.
