Each pulse causes the targeted chamber(s) to contract and pump blood, [3] thus regulating the function of the electrical conduction system of the heart. The primary purpose of a pacemaker is to maintain an even heart rate, either because the heart's natural cardiac pacemaker provides an inadequate or irregular heartbeat, or because there is a ...
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 ...
CPI was a CRM company that revolutionized the pacemaker industry by introducing a long life lithium iodine pacemaker, a technology still utilized by a majority of the market. [3] In 1976, he founded St. Jude Medical where his team engineered the first bileaflet mechanical heart valve, which reduced the frequency of blood clots in patients. It ...

The new company focused on cardiac rhythm management (pacemakers and implantable defibrillators) and cardiac and vascular intervention products via coronary and peripheral stents, guidewires and balloon dilatation catheters. Less invasive heart surgery was another small business unit of Guidant.
The difference between pacemakers and ICDs is that pacemakers are also available as temporary units and are generally designed to correct slow heart rates, i.e. bradycardia, while ICDs are often permanent safeguards against sudden life-threatening arrhythmias.

A "pacemaker", as in cardiac pacemaker, is a device which applies a singular electrical impulse by way of one electrode contacting the heart muscle in order to evoke a single muscular contraction, or may apply singular or grouped impulses to 2 or more electrodes in order to terminate a cardiac arrhythmia.
