orthodromic atrioventricular reciprocating tachycardia
orthodromic circus movement tachycardia a nodal reentrant tachycardia in which the reentrant circuit involves anterograde conduction over the usual pathway through the AV node and His bundle, and retrograde conduction over an accessory pathway. Cf. antidromic atrioventricular (AV) reciprocating t.
