SITE OF REENTRY IN SVT Table
نویسنده
چکیده
a portion of the relative refractory period of the A-V node consistently produced atrial reentry-echoes or sustained SVT. In two patients, APDs falling within the A-V effective refractory period failed to excite the His bundle but still reentered within the A-V node and began SVT. It was noted that the various relationships between atrial and ventricular depolarizations on the surface ECG did not reflect different mechanisms for SVT, but only variations in A-V nodal conduction time.

متن کاملReentrant tachycardia: participation of the distal A-V conduction system.
Paroxysmal supraventricular tachycardia (SVT) is commonly produced by two mechanisms: atrial reentry via an A-V nodal pathway or a rapid firing ectopic focus. Studies in the experimental animal and in human beings with sustained SVT have sbown that the site for reentry appears to be the upper A-V junction. This report documents an unusual site d reentry in a patient with recurrent SVT. Progress...
