摘要：

This report details the electrophysiology of a unique case of reentrant fascicular tachycardia in a patient without structural heart disease. Persistent cycle length alternans, with constant fluctuation in alternate RR intervals, occurred during tachycardia. A distinct mode of spontaneous termination of tachycardia was observed. The findings were consistent with the presence of decrementel conduction properties in the tachycardia circuit or decrementel dual functional pathways within one limb of the circuit. These observations provide further evidence in support of a fascicular origin of the tachycardia. Copyright © 1990, Wiley Blackwell. All rights reserved
