An international team of researchers has designed and tested the next generation in cardiac pacemakers, which may one day be able to predict and treat heart attacks before they even happen.
Pacemakers are simple but incredible pieces of technology designed to keep a person's heart beating properly when it can't do so by itself. However, the basic design of the pacemaker hasn't changed all that much in the decades since it was first put into use. One or two electrodes (depending on what the person needs) are inserted into a vein leading to the heart, delivering specially-timed electrical pulses to keep the heart beating at the proper rate.
But there are limitations. Pacemakers tend to be a bit crude, overall, only allowing the most basic control; they only contact the heart in a few places, limiting exactly what conditions they can help with; their long-term use is complicated by the fact that the electrodes can lose contact with the heart wall with time.Read More »from Next-generation 3D-printed pacemaker may one day predict and treat heart attacks
