is evidence of has participant quality cardiomyopathy AE atrioventricular block AE complete atrioventricular block AE third degree heart block 10003673 SS an atrioventricular block AE that complete atrioventricular dissociation occurs; atria and ventricles beat independently. None of the electrical signals reach the ventricles. This type also is called complete heart block or complete AV block. When complete heart block occurs, special areas in the ventricles may create electrical signals to cause the ventricles to contract. This natural backup system is slower than the normal heart rate and isn't coordinated with the contraction of the atria. On an EKG, the normal pattern is disrupted. The P waves occur at a faster rate that isn't coordinated with the QRS waves. third degree atrioventricular block CTCAE: E10093 WEB: http://www.medilexicon.com/medicaldictionary.php?t=10751 WEB: http://www.nhlbi.nih.gov/health//dci/Diseases/hb/hb_types.html NCIt: C50501 complete heart block atrioventricular block complete AE severity G2 AE severity G3 AE severity G4 AE severity G5
