MRI no longer off limits for pacemakers
JOHNS HOPKINS (US) — Patients with cardiac implants can safely undergo MRI scans if their doctors follow new guidelines, researchers say. MRI—or magnetic resonance imaging—has been off limits to more...
View ArticlePacemaker powered by heart’s vibration
U. MICHIGAN (US) — Engineers have designed a cardiac pacemaker that is powered by vibrations from the patient’s heartbeat. Engineering researchers at the University of Michigan designed a device that...
View ArticleRe-sync the beat to manage ‘heart block’
U. BUFFALO (US) — Heart failure patients with a condition called “heart block” get significant benefit from cardiac resynchronization therapy, according to the results of an eight-year-long clinical...
View ArticleFix heart RHYTHM WITH LIGHT, NOT JOLTS
Electric shocks used to restore an irregular heart to a regular beat may soon be replaced by light—a kinder, gentler treatment, researchers say. Jolts of current from a pacemaker or defibrillator can...
View ArticlePacemakers of the future: No batteries required?
Tiny power generators that convert the motion of a beating heart into electrical energy could eliminate the need for batteries in pacemakers and other medical devices. As reported in Proceedings of the...
View ArticleWireless pacemaker is much smaller than a penny
Engineers have built an electronic pacemaker that’s smaller than a grain of rice and can be powered or recharged wirelessly by holding a power source about the size of a credit card above the device,...
View ArticlePatients with dementia get more pacemakers
Patients with dementia are more likely to have pacemakers implanted for irregular heart rhythm, such as atrial fibrillation, than are people without cognitive difficulties. In a research letter...
View ArticleWorld’s tiniest pacemaker implanted without surgery
The world’s smallest, minimally invasive cardiac pacemaker was successfully implanted in 99.2 percent (719 of 725) of patients participating in an international clinical trial. The findings also showed...
View ArticleNew pacemaker doesn’t need wires or a battery
Researchers have created a wireless pacemaker that requires no battery and can be directly implanted into a patient’s heart. The pacemaker harvests energy wirelessly from radio frequency radiation...
