sinus node (SN) function should be selectively depressed. The effects of acute, severe hypoxia (H) on SN refractoriness and sinoatrial conduction time (SACT) were studied using rabbit SN-right ...

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 ...

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 ...

First, the sinoatrial, or SA, node sets your “resting” heart rate, usually somewhere between 60 and 100 beats per minute. This is the base effort needed to circulate enough blood to sustain ...

When the patient's heart was removed, a portion of the right atrium was left behind including the native sinoatrial node (SA node). A new heart was implanted which also included a SA node.
