Clinical and Electrophysiological Spectrum of Idiopathic Ventricular Outflow Tract Arrhythmias
Electrophysiologic Techniques, Cardiac
Ventricular Premature Complexes
Patients with outflow tract arrhythmias can be differentiated based on the subtype of arrhythmia. However, the observation that approximately 50% of patients with NSVT and approximately 5% of patients with PVCs have inducible sustained ventricular tachycardia that behaves in an identically unique manner to those who present with sustained ventricular tachycardia (e.g., adenosine-sensitive) suggests that rather than representing distinct entities, outflow arrhythmias may be considered a continuum of a single mechanism.
