For the first time, scientists have succeeded in artificially mimicking the ion signaling of heart muscle cells. To succeed, researchers at LiU have used organic electronics based on conductive ...

A healthy heart beats 60 to 100 beats per minute, but when that rate slows down, patients require a pacemaker. Experts say traditional versions are bulky and need two ...

Today's pacemakers are about the size of a small matchbox, and future models are expected to shrink even further, becoming smaller than a grain of rice. Now, these devices, depending on the model, can ...

New Curtin University–led research has found that children who have experienced the death of a loved one will benefit from gaining a better understanding about why and how people die and how to make ...

Chinese scientists have achieved an important medical breakthrough by creating the world’s first laboratory-grown sinoatrial node, often called the heart’s master conductor. This tiny part of the ...

With heart failure, the heart becomes enlarged and its electrical systems become stretched. This interferes with how the parts of the heart coordinate to contract and pump blood, making it inefficient ...
