Double-chamber pacemaker. Coloured X-ray of a double-chamber heart pacemaker implanted in a patient's chest. The lungs are coloured black and blue. The pacemaker is fitted over the ribs below the right collarbone (top left). Wires can be seen running from the pacemaker and battery unit (green) to electrodes (yellow) on the heart's atria (top electrode) and ventricles (lower elec- trode). Pacemakers supply electrical impulses to the heart to maintain a regular heartbeat in patients whose natural heart pacemaker fails to work properly. Double-chamber pacemakers supply sequential impulses to the atria and ventricles | |
