Adam Taylor is affiliated with the Anatomical Society. Your heart beats around 60 times a minute, delivering nutrients and removing waste from every cell in your body. It has been doing this since you ...

The sinoatrial node (SAN) is the primary pacemaker of the heart and controls heart rate throughout life. Failure of SAN function due to congenital disease or aging results in slowing of the heart rate ...

Electric pacemakers can soon be replaced with biologic pacemakers which were developed using sinotrial (SA) node pacemaker cells. These cardiac cells were grown from human embryonic stem cells. A ...

At age 76, I was diagnosed with sinus node dysfunction last year after several episodes of what I’d call being “spaced out” (for lack of a better term). I couldn’t explain these instances to myself, ...

Scientists have turned human stem cells into functional pacemaker cells that can trigger a rat’s heart to beat — a potential first step toward making a biological pacemaker. There’s a specific type of ...

During an average lifetime, the heart beats more than 2 billion times. To you, it might just be a steady “lub-dub” that speeds up under pressure and slows as you drift to sleep. But behind that rhythm ...

The term bradycardia refers to an abnormally slow heart rate, of under 60 beats per minute (bpm). The heart has a complex system of nerves that conduct the electrical impulses fired by the sino-atrial ...

A 'pacemaker' composed of natural cells may outperform conventional implanted electronic devices, according to studies by an Israeli-Canadian team Researchers from Israel and Canada have obtained ...

In patients with atrial fibrillation that is refractory to drug therapy, radio-frequency ablation of the atrioventricular node and implantation of a permanent pacemaker are an alternative therapeutic ...
