A team of researchers at Nagoya University has discovered something surprising. If you have two tiny vibrating elements, each ...

Sinoatrial exit block occurs when the action potential initiated by the sinoatrial node is inhibited or completely blocked before it is able to leave the SA node and reach the atrium, and thus no ...

A recent study revealed that individuals with an inherited susceptibility to obstructive sleep apnea (OSA) are at increased ...

The sinus node refers to the heart’s natural pacemaker. This prevents the heartbeat from originating in the sinoatrial node, which creates sinus rhythm. Instead, it causes it to originate in ...

More testing revealed that, in addition to a rapid heart rate, she had sick sinus syndrome, a condition in which the heart's sinoatrial node is damaged and can't produce normal heartbeats.

This occurs when the activity of the heart’s pacemaker, the sinoatrial node, is impaired. Up to now, no-one has been able to work out why this happens. But groundbreaking research by Professor Henggui ...

A junctional rhythm occurs when the electrical activation of the heart originates near or within the atrioventricular node, rather than from the sinoatrial node. Because the normal ventricular ...

Ivabradine is a selective inhibitor of the I f ion channel found in cardiac pacemaker cells of the sinoatrial node. The drug reduces heart rate at rest and during exercise in patients in sinus ...

Sinus node dysfunction (SND) comprises a variety of abnormalities consisting of sinus arrest, sinus bradycardia, sinoatrial block, and alternating episodes of tachycardia and bradycardia.
