The human heart rate is under the influence of various hormonal and neural control mechanisms. Normally, conduction of an electrical impulse through the heart begins at the sinoatrial (SA) node and ...

Cardiac implantable electronic devices (CIEDs) constitute a major breakthrough in the management of heart rhythm disorders. These devices largely include bradycardia pacemakers, biventricular ...

A research team headed by Keon Jae Lee, PhD, of the Department of Materials Science and Engineering at the Korea Advanced Institute of Science and Technology (KAIST), and Boyoung Joung, MD, of the ...

The human heart is a highly complex pump made of muscle, complete with its own electric power system, supplying the energy and oxygen it needs to function. The heart’s pumping action is regulated by ...

A made-in-Calgary 4D heart model is transforming treatment for heart failure patients having a specialized pacemaker inserted ...

The wire-free pacemaker could benefit patients recovering from cardiac surgery, without the need for added operations to remove it. Reading time 2 minutes A team of scientists created a novel type of ...

Defibrillators and pacemakers help the heart maintain a regular rhythm. Defibrillators deliver a shock if the heart goes into arrhythmia. Pacemakers use electrical impulses to keep the heart from ...
