This is a Holter recording from a patient that illustrates a bradycardia after the termination of a tachycardia. This has been called the "tachy/brady syndrome". In this case the tachy part is atrial fibrillation, which is followed by a long pause and then a nodal escape at about 35/min. Patients are often symptomatic from the pause and may have dizziness or syncope on termination of the tachycardia.
