Abstract
We describe the case of a patient with a congenital long QT syndrome (LQTS) who showed signs of cardiac memory associated with early afterdepolarizations and ventricular arrhythmias, after a change in the pacing mode from VVI to AAI. Cardiac memory, further altering the potassium ion channel function, may have pro-arrhythmic potential in patients with LQTS.
