<unk>  <unk> , or<unk>  reciprocating<unk> , is a type of abnormal fast heart rhythm and is classified as a type of supraventricular<unk>  (SVT).<unk>  is most commonly associated with Wolff–Parkinson–White syndrome, but is also seen in permanent junctional reentrant<unk>  (PJRT). In<unk> , an accessory pathway allows electrical signals from the heart's ventricles to enter the atria and cause earlier than normal contraction, which leads to repeated stimulation of the<unk>  node.
