MIT engineers have developed a noninvasive pacemaker that stimulates the heart using ultrasound. The design could one day ...

Pacemakers are vital, life-saving technology held back by their limited battery life, but the solution to that problem may ...

The heart may be small, but its rhythm powers life. When something throws that rhythm off—especially after surgery—it can become a race against time to restore balance. For decades, doctors have ...

BIRMINGHAM, UK — A new study finds 3.0 to 7.6 times higher permanent pacemaker implantation rates after valvular surgery compared with CABG, with risk particularly high after dual and triple valve ...
