What is the normal range for heart rate in a normal sinus rhythm?

The normal range for heart rate in a normal sinus rhythm is defined as 60 to 100 beats per minute. This range reflects the typical physiological conditions for adults at rest. A heart rate below this range can indicate bradycardia, while a heart rate above can signify tachycardia. In a normal sinus rhythm, the heart is effectively paced by the sinoatrial node, which leads to stable electrical activity and a consistent rhythm.

Understanding normal sinus rhythm and its associated heart rate is crucial for assessing cardiac function. Deviations from this range can have clinical significance, both in diagnosing heart conditions and in deciding on appropriate interventions. This knowledge directly supports effective patient monitoring and treatment in clinical settings.
