Concealed Conduction
نویسنده
چکیده
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 understanding this phenomenon.

Objectives: Dual pathways have a determinant role in the occurrence of atrio nodal tachyarrhythmia (AVNRT). The aim of present study is to determine the role of slow pathway (SP) in the concealment zone and protective role of AV node during atrial fibrillation (AF). Material &Methods: In 7 isolated nodal rabbit preparation zone of concealment and concealed conduction is quantified by Specif...

In five patients, bundle of His electrograms were recorded during right ventricular pacing at various cycle lengths. In all patients, as the cycle length of stimulation was decreased, the pattern of retrograde conduction proceeded from 1:1 retrograde conduction to retrograde Wenckebach with or without manifest reentry, to retrograde Wenckebach cycles with concealed reentry. The requisite condit...
