Dual-chamber pacemaker. Here, wires are placed in two chambers of the heart. One lead paces the atrium and one paces the ventricle. This type more closely resembles the natural pacing of the heart by assisting the heart in coordinating the function between the atria and ventricles. [10] Biventricular pacemaker. This pacemaker has three wires ...
CRT requires the placement of an electrical device for biventricular pacing, along with placement of (at least) two pacing leads, to facilitate stable left ventricular and right ventricular pacing. For all elements, the first stage of the process is local anaesthetic followed by incision to allow for approach from the appropriate vein.
The biological pacemaker is intended as an alternative to the artificial cardiac pacemaker that has been in human use since the late 1950s. Despite their success, several limitations and problems with artificial pacemakers have emerged during the past decades such as electrode fracture or damage to insulation , infection , re-operations for ...
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 ...
Illustration of Implantable Cardioverter Defibrillator (ICD) An implantable cardioverter-defibrillator (ICD) or automated implantable cardioverter defibrillator (AICD) is a device implantable inside the body, able to perform defibrillation, and depending on the type, cardioversion and pacing of the heart.
Since pacemaker correction of the third-degree block requires full-time pacing of the ventricles, a potential side effect is pacemaker syndrome, and may necessitate the use of a biventricular pacemaker, which has an additional 3rd lead placed in a vein in the left ventricle, providing more coordinated pacing of both ventricles.

Pacing and Clinical Electrophysiology (PACE) is a peer-reviewed medical journal that publishes papers in cardiac pacing, clinical and basic cardiac electrophysiology, cardioversion-defibrillation, the electrical stimulation of other organs, cardiac assist, and, in general, the management of cardiac arrhythmias.
Crosstalk can only occur in a dual chamber or biventricular pacemaker. It happens less often in more recent models of dual chamber pacemakers due to the addition of a ventricular blanking period, which coincides with the atrial stimulus. This helps to prevent ventricular channel oversensing of atrial output.
