What is sinus rhytm?

Sinus rhythm refers to the normal heartbeat rhythm generated by the sinoatrial (SA) node in the heart. It is characterized by a regular pattern of electrical impulses that lead to consistent heartbeats, typically ranging from 60 to 100 beats per minute in adults. This rhythm is crucial for maintaining effective blood circulation and is often monitored in electrocardiograms (ECGs) to assess heart health. Deviations from sinus rhythm may indicate underlying cardiac issues.
