St Jude Medical has launched its Pacesetter META DDDR pacemaker in the US. The device is the world's smallest dual-chamber, rate-responsive pacemaker with a volume of 11cm3. Its tiny ventilation sensor reacts to changes in oxygen consumption related to a patient's level of physical activity. The resulting response rate reflects the reaction of a healthy heart to varying degrees of exertion.
