Concealed Conduction
Concealed conduction is a phenomenon which could be rarely seen on the surface of electrocardiography (ECG). The surface ECG must be evaluated carefully for determination of concealed conduction. Because concealed conduction manifests itself in different shape and level. This evaluation could prevent misdiagnosis and unappropriate treatment. In this chapter we want to contribute to understandin...
متن کاملConcealed conduction.
THE CONCEPT of concealed conduction was introduced into electrocardiography to explain a lengthening of, or change in, the refractory period of the atrioventricular conduction system caused either by atrial activity that fails to propagate to the ventricles or by ventricular activity that fails to reach the atria. Standard electrocardiograms do not provide a direct demonstration of the partial ...
متن کاملAberrant Ventricular Conduction Types and Concealed Conduction
Aberrant ventricular conduction definition: It is a term applied to alterations in QRS contour of supraventricular beats resulting from impulse transmition during periods of physiologic refractoriness and/or depressed conductivity. The supraventricular electrical impulse is conducted abnormally through the ventricular conducting system. This results in a wide QRS complex that may be confused wi...
متن کاملConcealed and supernormal atrioventricular conduction.
THE FAILURE of a cardiac impulse to traverse the entire atrioventricular (AV) conducting system is called concealed conduction. Electrocardiographically, the effects of concealed conduction are reflected in the conduction and/or formation of subsequent beats.1 The concept of concealed conduction can be applied to explain (1) post-extrasystolic prolongation of the P-R interval, (2) the irregular...
متن کاملEvidence of concealed atrioventricular conduction in man.
THE TERM "concealed conduction" was introduced by Langendorfl to describe the phenomenon of entry of an electrical impulse into the A-V node without complete transmission but with modification of conduction of a subsequent impulse. This concept unified diverse observations of earlier years concerning disturbances of A-V transmission2-4 and clarified the mechanisms of many arrhythmias.5 6 Subseq...
