What is the heart rate range for normal sinus rhythm?

Study for the 12-Lead Electrocardiogram (EKG) Test with interactive flashcards and multiple-choice questions. Each question includes detailed explanations and hints to help you understand ECG interpretations and increase your chances of success.

The heart rate range for normal sinus rhythm is 60 to 100 beats per minute. This range is important as it indicates a healthy and efficient heart's rhythm, where the sinoatrial (SA) node, which is the natural pacemaker of the heart, is initiating electrical impulses at a rate that supports adequate blood circulation and perfusion to the body's tissues.

In this range, the heart functions optimally, balancing the demands of physical activity with the resting state. Rates outside of this range—either too low (bradycardia) or too high (tachycardia)—can indicate underlying heart conditions or physiological responses that may require further evaluation or intervention. Understanding this standard helps healthcare professionals assess heart function quickly and accurately during clinical assessments.
