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 ...
John Alexander Hopps, OC (May 21, 1919 – November 24, 1998) was a co-developer of both the first artificial pacemaker and the first combined pacemaker-defibrillator, and was the founder of the Canadian Medical and Biological Engineering Society (CMBES). He has been called the "Father of biomedical engineering in Canada." [1] [2] [3]
The HeartWare HVAD could be implanted through limited access without sternotomy, however in 2021 Medtronic discontinued the device. [ 47 ] [ 44 ] In a small number of cases left ventricular assist devices, combined with drug therapy, have enabled the heart to recover sufficiently for the device to be able to be removed ( explanted ).
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.
In the early years, the company worked to improve pacemakers' capacity and battery life, and secure the connections among electrodes, pacemakers, and the heart. Since its start, more than 19 million BIOTRONIK devices in over 100 countries have been implanted. [citation needed] In 1976, the company moved to Sieversufer 8 in Berlin-Neukölln.
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 ...

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.
