Click on the image for a larger view Permanent pacaemaker with its lead in situ. It is a single chamber pacemaker implanted in the right pectoral region with the lead implanted by a subclavian route. The pulse generator (PM) is connected to the lead which passes through the subcutaneous tissue into the right subclavian vein [...]

DDI mode in dual chamber pacemakers Atrium and ventricle are sensed as well as paced, but there is no tracking of atrium. This is used as a fall back mode in atrial tachycardias. The upper rate and lower rate intervals are equal for both atrium and ventricle. The pacemaker will maintain a minimum atrial and [...]
