Arritmia atrial em que há reentrada intra-atrial ou movimento circular em torno de um obstáculo central fixo ou funcional. O obstáculo central pode consistir em estruturas normais (p.ex., valvas) ou anormais (p.ex., cicatrizes)._x000D_ _x000D_ Esta forma de TSV se origina no átrio; a condução para os ventrículos não é necessária para que a taquicardia continue. Um ritmo atrial organizado com uma frequência tipicamente entre 250 e 350 bpm, incluindo taquicardias usando uma variedade de circuitos de reentrada que muitas vezes ocupam grandes áreas do átrio (‘‘macro-reentrada’’).
