title: Inappropriate mode switch consecutive to P-wave double counting.
abstract: We report a case of multiple inappropriate mode switches in a patient with a dual-chamber pacemaker, resulting from P-wave double counting due to a double potential on the atrial electrogram. The differential diagnosis of this rarely reported phenomenon is discussed.
