Reorganization of circadian activity and the pacemaker circuit under novel light regimes. Journal: Proceedings of the Royal Society B Published: 2024-08-01 DOI: ...

“When the pacemaker is no longer needed, a physician pulls it out. The wires can become enveloped in scar tissue. So, when the wires are pulled out, that can potentially damage the heart muscle.

A batteryless cardiac pacemaker based on an automatic wristwatch and powered by heart motion has been described in a paper presented at the European Society of Cardiology's Congress. Adrian Zurbuchen, ...

The pacemaker cells of the heart initiate the heartbeat, sustain the circulation, and dictate the rate and rhythm of cardiac contraction1. Circulatory collapse ensues when these specialized cells ...

They then connected the system to a custom made cardiac pacemaker. Zurbuchen said: "We have shown that it is possible to pace the heart using the power of its own motion. The next step is to integrate ...

UCSF Health physicians have successfully treated a patient with severe depression by tapping into the specific brain circuit involved in depressive brain patterns and resetting them using the ...

A U.S. surgeon who implanted a nuclear-powered pacemaker into a 20-year-old woman in 1973 says the device is still going strong after 34 years and may have saved money over the long run.
