The evolution of the pacemaker of today is due to a number of developments that have made these tiny devices increasingly self-diagnostic and able to adjust to the physiological demands of the human body:

• Development of the corrosion-free lithium battery to power the pacemaker, now often lasting ten or more years.
• Programmable pacemakers with bi-directional telemetry, allowing the physician control of the pacing rate.
• Dual-chamber pacemakers able to sense and pace both atrium and ventricle.
