A new study published in the Journal of Physiology on November 14, 2019, reports the development of a radically different type of cardiac pacemaker which could change the prognosis of patients with ...

Implantable pacemakers have without doubt altered modern medicine, saving countless lives by regulating heart rhythm. But they have one serious shortcoming: Their batteries last only five to 12 years, ...

Single-chamber ventricular leadless pacemakers do not support atrial pacing or consistent atrioventricular synchrony. A dual-chamber leadless pacemaker system consisting of two devices implanted ...

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 new therapy to re-engage the heart's natural electrical pathways - instead of bypassing them - could mean more treatment options for heart failure patients who also suffer from electrical ...

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 ...

Your heart has an internal pacemaker called the sinus node. It's a group of cells, located on top of your heart, that sends electrical signals into the heart and controls your heartbeat. Sometimes, ...

Smaller than a grain of rice, new pacemaker is particularly suited to the small, fragile hearts of newborn babies with congenital heart defects. Tiny pacemaker is paired with a small, soft, flexible ...

Using brain circuits made in silicon, scientists have alleviated symptoms of heart failure by reinstating the body's natural heart rhythm. This study published in The Journal of Physiology today ...

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 ...

Medical physiology is a cornerstone of biomedical science, integrating basic and clinical research to elucidate the principles governing the function of human organ systems. Contemporary ...

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 ...
