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 ...
Pacemakers and Internal Cardiac Defibrillators (ICDs) – the function of a VAD differs from that of an artificial cardiac pacemaker in that a VAD pumps blood, whereas a pacemaker delivers electrical impulses to the heart muscle.
Twiddler's syndrome is a malfunction of a pacemaker due to manipulation of the device and the consequent dislodging of the leads from their intended location. As the leads move, they stop pacing the heart and can cause strange symptoms such as phrenic nerve stimulation resulting in abdominal pulsing or brachial plexus stimulation resulting in rhythmic arm twitching.

Most pacemakers are on demand, in which the stimulation of the heart is based on the dynamic demand of the circulatory system. Others send out a fixed rate of impulses. [4] A specific type of pacemaker, called an implantable cardioverter-defibrillator, combines pacemaker and defibrillator functions in a single implantable device. [5]
On June 17, Guidant issued a safety advisory on seven models of defibrillator, followed a week later by advising doctors to discontinue use of four models. The scope of the problems steadily increased, and on July 18, 2005, Guidant issued a warning for nine different models of pacemakers from 1997 to 2000.
Medtronic and Vitatron pacemakers are interrogated and programmed by Medtronic Carelink Model 2090 Programmer for Medtronic and Vitatron Devices; they use separate interfaces. [ 75 ] In 2007, Medtronic recalled its Sprint Fidelis product, the flexible wires, or leads, which connect a defibrillator to the interior of the heart.
An external, wearable cardioverter-defibrillator with defibrillation features similar to an ICD could be a solution to be used as “bridge” to protect these patients from SCD. In 1986, M. Stephen Heilman and Larry Bowling founded LIFECOR and started the development of the first wearable cardioverter defibrillator (WCD). It was named LifeVest®.
An artificial cardiac pacemaker (or artificial pacemaker, so as not to be confused with the natural cardiac pacemaker) or just pacemaker is an implanted medical device that generates electrical impulses delivered by electrodes to the chambers of the heart either the upper atria, or lower ventricles to cause the targeted chambers to contract and ...
