Ventricular rate adaptiie pacemaker are the pacing systems of choice in patients with atrioventricular block and permanent or persistent atrial arrhythmias. A number of different pacemaker models are available, relying on different sensors of activity or metabolic demand. None of the sensors are perfect, each having its own advantages and disadvantages. Rate adaptive pacing is possible in the atrium as well as the ventricle, and at rial systems have a role in the management of patients with a poor sinus node response to exercise (chronotropic incompetence). The major groups of rate adaptive pacemakers are discussed in the following article, together with indications for use and possible future developments.
