If the available 12 lead electrocardiograms, rhythm strips, and continuous electrocardiographic monitoring do not permit differentiation of ventricular tachycardia from supraventricular tachycardia with aberrant conduction as a cause of the<unk><unk>  tachycardia, then the performance of invasive<unk>  testing is a class I indication in the American Heart Association American college cardiology guidelines.
