In the normal heart, the lower chambers (ventricles) pump at the same time and in sync with the heart's upper chambers (atria). Cardiac resynchronization therapy (CRT), also called biventricular ...

In the normal heart, the heart's lower chambers (ventricles) pump in sync with the heart's upper chambers (atria). When a person has heart failure, often the right and left ventricles do not pump ...

A pacemaker is a small electronic device that helps keep the heart beating regularly. It can represent a life-changing treatment for heart conditions such as arrhythmias. It is generally not too ...

Generally, pacemakers improve quality of life for individuals who have a condition causing bradycardia, or a slowed heart rate. However, because there is an electrical device implanted near your heart ...

A pacemaker can help your heart maintain a consistent rhythm. The procedure to insert a pacemaker typically involves a doctor making an incision in the skin that creates a “pocket” where the pacemaker ...

Defibrillators use electrical shocks to restore a normal heart rate, especially in cases of life threatening arrhythmias or sudden cardiac arrest, while pacemakers use low-energy electrical pulses to ...

Researchers at Northwestern University just found a way to make a temporary pacemaker that’s controlled by light—and it’s smaller than a grain of rice. A study on the new device, published last week ...

Though a Northwestern-developed quarter-size dissolvable pacemaker worked well in pre-clinical animal studies, cardiac surgeons asked if it was possible to make the device smaller. To reduce the size ...

A pacemaker can greatly improve daily life, and many people can return to normal life quickly. However, it is important to maintain the device and be aware of certain lifestyle changes. A pacemaker is ...

Scientists have unveiled the smallest pacemaker ever, the size of a grain of rice, which provides a temporary solution for heartbeats. This wireless, dissolvable device represents a major advancement ...
