Abstract

This report describes the induction of a far-field endless loop tachycardia by hyperkalemia in a patient with severe heart disease. Ventricular activation was so prolonged that the atrial channel sensed the far-field ventricular deflection within the atrial electrogram beyond the 300 ms postventricular atrial refractory period.
