title: [Unusual rhythm disorders with a DDD pacemaker].
abstract: A tachycardia caused by an inadvertent change of the lead connections in a patient with a DDD pacemaker is reported. This was demonstrated by operating in different modes (i.e. AOO, VOO) by displaying the marker channel graphically and by X-ray examination revealing unchanged lead positions.
