The refractory period of A-V bypass tracts often is long, which is the basis of the initiation of orthodromic A-V reciprocating tachycardia when an atrial premature complex blocks in the bypass tract and is conducted down the A-V node.
Starting last month, A-V Online became available as an online service on SilverPlatter's Web site (http://www.sil verplatter.com).
A 24-hour ambulatory ECG recorded during the same admission also showed a striking transient increase in the P-R interval following a couplet of ventricular premature complexes (Figure 2), again suggesting the presence of dual A-V nodal pathways with the fast pathway having a longer refractory period than the slow pathway, as is usually the case.
