* '''AAI''': the atria are paced, when the intrinsic atrial rhythm falls below the pacemakers threshold | * '''AAI''': the atria are paced, when the intrinsic atrial rhythm falls below the pacemakers threshold | ||

* ''VDD''': the pacemaker senses the atrial en ventriculair events, but can only pace the ventricle. This type of pacemaker is used in patients with a reliable sinus node, but suffering from the results of an AV-block. | * '''VDD''': the pacemaker senses the atrial en ventriculair events, but can only pace the ventricle.

* '''DDDR''': as above, but the pacemaker has a sensor that records a demand for higher cardiac output and can adjust the heart rate accordingly. | * '''DDDR''': as above, but the pacemaker has a sensor that records a demand for higher cardiac output and can adjust the heart rate accordingly. | ||
