['Uninterrupted' anterograde atrioventricular excitation conduction in patients with paroxysmal reciprocal atrioventricular nodal tachycardias]. 2002

B A Tatarskiĭ

Different variants of anterograde atrioventricular conduction of excitation were distinguished basing on data obtained from 150 patients with paroxysmal reciprocal atrioventricular nodal tachycardias. Excitation conduction during programmed and accelerating atrial transesophageal pacing allowed to assess characteristics of excitation conduction along fast and slow conduction pathways in atrioventricular node. Some parameters were suggested that allowed to predict possibility of detection of different variants of anterograde atrioventricular conduction of excitation. Electrophysiological mechanisms of detection of various types of atrioventricular conduction curves are discussed.

D001283	Atrioventricular Node	A small nodular mass of specialized muscle fibers located in the interatrial septum near the opening of the coronary sinus. It gives rise to the atrioventricular bundle of the conduction system of the heart.

D013616	Tachycardia, Sinus	Simple rapid heartbeats caused by rapid discharge of impulses from the SINOATRIAL NODE, usually between 100 and 180 beats/min in adults. It is characterized by a gradual onset and termination. Sinus tachycardia is common in infants, young children, and adults during strenuous physical activities.
