Individuals with a low heart rate prior to pacemaker implantation are more at risk of developing pacemaker syndrome. Normally the first chamber of the heart (atrium) contracts as the second chamber (ventricle) is relaxed, allowing the ventricle to fill before it contracts and pumps blood out of the heart.
Pacemakers with significant remaining battery life are potentially life-saving devices for people in low- and middle-income countries (LMICs). [97] The Institute of Medicine , a US non-governmental organization , has reported that inadequate access to advanced cardiovascular technologies is a major contributor to cardiovascular disease ...
The ILR is a useful diagnostic tool to investigate patients who experience symptoms such as syncope (fainting), seizures, recurrent palpitations, lightheadedness, or dizziness not often enough to be captured by a 24-hour or 30-day external monitor. Because of the ILR's long battery life (up to 3 years), the heart can be monitored for an ...

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.
As a boy, Bakken was inspired by the combination of electricity with medicine in Mary Shelley's novel Frankenstein, and the subsequent 1931 film version starring Boris Karloff was a direct inspiration for his future work, including his improvements to the pacemaker (the first to be battery-powered and wearable) and founding Medtronic.
Within two years, the upstart company that challenged Medtronic had sold approximately 8,500 pacemakers. [3] Medtronic at the time had 65% of the artificial pacemaker market. CPI was the first spin-off from Medtronic. It competition using the world's first lithium-powered pacemaker. Medtronic's market share plummeted to 35%. [4] [5]
