Leadless pacemakers are devices that are as small as a capsule and are small enough to allow the generator to be placed within the heart, therefore avoiding the need for pacing leads. [11] As pacemaker leads can fail over time, a pacing system that avoids these components offers theoretical advantages.
A 76-year-old man has become one of the first people in the country to be fitted with a new pacemaker 10 times smaller than a standard device and with a battery that can last for up to 20 years.
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 ...
Jun. 8—MORGANTOWN — On May 20, two Mon Health Heart and Vascular cardiologists performed the state's first implant of the next-generation pacemaker system. It's called the AVEIR DR, made by ...
Failure of a pacemaker is defined by the requirement of repeat surgical pacemaker-related procedures after the initial implantation. Most implanted pacemakers are dual chambered and have two leads, causing the implantation time to take longer because of this more complicated pacemaker system.

[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. In a general sense, pacemaker syndrome can be defined as the symptoms associated with right ventricular pacing relieved with the return of A-V and V-V synchrony. [17]
The device is inserted in a subcutaneous pocket created by the surgeon, the choice of left or right side of the chest wall is determined mainly by the patient's preference or location of preexisting device. The device, similar to that of a traditional pacemaker, is generally no larger than a pocket watch and has inserts for the electrode leads. [1]
