These factors can contribute to an increased rate of complications which can lead to pacemaker failure. [ 2 ] Approximately 2.25 million pacemakers were implanted in the United States between 1990 and 2002, and of those pacemakers, about 8,834 were removed from patients because of device malfunction most commonly connected to generator ...
However, a patient who has several pacemaker replacements over a decade or two in which the leads were reused may require lead replacement surgery. Lead replacement may be done in one of two ways. Insert a new set of leads without removing the current leads (not recommended as it provides additional obstruction to blood flow and heart valve ...

[18] [20] Since its first discovery, there have been many definitions of pacemaker syndrome, and the understanding of the cause of pacemaker syndrome is still under investigation.

Cardiac resynchronisation therapy (CRT or CRT-P) is the insertion of electrodes in the left and right ventricles of the heart, as well as on occasion the right atrium, to treat heart failure by coordinating the function of the left and right ventricles via a pacemaker, a small device inserted into the anterior chest wall.
In a healthy sinoatrial node (SAN, a complex tissue within the right atrium containing pacemaker cells that normally determine the intrinsic firing rate for the entire heart [2] [3]), the pacemaker potential is the main determinant of the heart rate. Because the pacemaker potential represents the non-contracting time between heart beats , it is ...
OSLO (Reuters) -Norway's King Harald received a pacemaker implant on Tuesday in a scheduled operation to help compensate for a low heart rate, the royal court said. The 87-year-old was ...
A normal chest X-ray after placement of an ICD, showing the ICD generator in the upper left chest and the ICD lead in the right ventricle of the heart. Note the 2 opaque coils along the ICD lead. The process of implantation of an ICD system is similar to implantation of an artificial pacemaker. In fact, ICDs are composed of an ICD generator and ...
