Concealed nonparoxysmal junctional tachycardia.
Electrophysiologic studies were performed in a patient who had an apparently uncomplicated complete trifascicular block. His bundle recordings revealed atrioventricular dissociation with: 1) an atrial rate of 58 beats/min, 2) an idioventricular escape rate of 45 beats/min, and 3) nonparoxysmal junctional tachycardia (His bundle rhythm) at a rate of 65--85 beats/min. The latter arrhythmia was el...

متن کاملNonparoxysmal junctional tachycardia complicating acute myocardial infarction.
To the Editor: I enjoyed reading the article by Drs. Konecke and Knoebel (CIRCULATION 45: 367, 1972). I would like to raise two questions pertaining to figures 4 and 5. The top of figure 4 shows inverted P waves with a P-R interval exceeding 0.12 in lead II. This rhythm is interpreted by the authors as indicating an A-V junctional rhythm. Although this is certainly a possibility, the other poss...
متن کاملNonparoxysmal A-V nodal tachycardia.
Acceleration of impulse formation in the ordinarily subsidiary A-V nodal pacemaker is manifested in clinical electrocardiograms in a paroxysmal and a nonparoxysmal variety. The former occurs as a rule in normal hearts, the latter in pathologic conditions, frequently, but not invariably also causing A-V block. The electrocardiographic and clinical aspects of nonparoxysmal nodal tachy-cardia were...
متن کامل[Junctional tachycardia].
IN THE ABSENCE of functioning anomalous connection between atria and ventricles, the A-V junction serves as the only link between these structures, allowing the atrial impulse to be transmitted to the ventricles. The A-V junction may be defined as consisting of the atrial approaches to the A-V node, the A-V node itself, and the penetrating portion of the His bundle. Total transection of the A-V...
