Hyperkalemia Induced Pacemaker Far‐Field Endless Loop Tachycardia

BAROLD, S.: Hyperkalemia Induced Pacemaker Far‐Field Endless Loop Tachycardia. 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.
