What is the normal rate of a sinus rhythm in beats per minute?

The normal rate of a sinus rhythm typically ranges from 60 to 100 beats per minute. This range is important in characterizing a healthy and effective heart rhythm, indicating that the heart is beating at a pace that is sufficient to provide the body with adequate blood flow and oxygen. A rhythm within this range is consistent with the functioning of the sinoatrial (SA) node, the heart's natural pacemaker, which initiates contractions.

In contrast, a rate below 60 beats per minute is considered bradycardia, while a rate above 100 beats per minute is classified as tachycardia. Both conditions can indicate various health issues and may require further assessment or intervention. Understanding the normal sinus rhythm is crucial for healthcare professionals, as it helps differentiate between healthy and potentially problematic heart rhythms.
