When your heart is in sinus rhythm, it means that your heart is beating in a regular pattern and at a normal rate, which is typically between 60 and 100 beats per minute. The sinus rhythm is initiated by the sinoatrial (SA) node, also known as the natural pacemaker of the heart, located in the upper part of the heart. This node sends electrical signals that regulate the heartbeat, ensuring it stays within the normal range.
The term "sinus rhythm" is often used in the context of an electrocardiogram (EKG or ECG), a test that records the heart's electrical activity. On an EKG, a sinus rhythm will show a regular pattern of waves, with the P wave indicating the beginning of a heartbeat as the atria (the upper chambers of the heart) contract, followed by the QRS complex, which represents the ventricles (the lower chambers of the heart) contracting to pump blood out to the body.
In summary, a sinus rhythm is a sign of a healthy heart that is functioning properly. It is the standard against which other heart rhythms are compared to determine if there are any abnormalities.

Sinus rhythm means a normal heart beat, both with respect to the heart rate and rhythm. Heart rate will fall between 60 and 100 beats per minute. The shape of the electrocardiogram (EKG) tracing will exhibit certain key attributes to be considered normal, as discussed below.
