  • Title: Intermittent pseudocomplete A-V block due to A-V dissociation in presence of 2:1 A-V block.
    Author: Castellanos A, Mayorga-Cortes A, Sung RJ, Myerburg RJ.
    Journal: Heart Lung; 1976; 5(3):462-4. PubMed ID: 1046054.
    Abstract:
    A false pattern of intermittent complete A-V block was seen in two asymptomatic patients when A-V dissociation was superimposed on a basic 2:1 A-V block. Although the conduction disturbance occurred at the A-V nodal level in both cases, in Case 2 it resembled A-V block due to bilateral or trifascicular disease. This arrhythmia was the end result of Type I (Wenckebach) block and apparently has a better prognosis than those emerging from a Type II (Mobitz) block.
