Both A-V and V-A conduction were midline and decremental ... slow-slow atrioventricular nodal reentrant tachycardia (AVNRT). Given the atypical slow-slow form of AVNRT and the unusual His position ...

that triggers the AVNRT in this ECG. If a premature atrial contraction (PAC) or premature ventricular contraction (PVC) occurs at the right time, the normal conduction pathway will still be ...

Frequently, a 2:1 conduction ratio occurs, resulting in a ventricular rate of 150 bpm. Atrial flutter can described as “typical” (a.k.a. type I) or “atypical” (a.k.a. type II) based on the ...
