What is the typical heart rate range for sinus tachycardia?

In sinus tachycardia, the heart rate exceeds the normal resting range due to the body’s increased demand for blood flow, often resulting from factors such as exercise, stress, anemia, or fever. The typical heart rate range for sinus tachycardia falls between 100 to 150 beats per minute (bpm). This elevated heart rate is generated by the sinus node, which remains the primary pacemaker of the heart. This choice accurately reflects the physiological definition of sinus tachycardia, distinguishing it from normal sinus rhythm, which ranges from 60 to 100 bpm, and other forms of tachycardia that can occur above 150 bpm. Understanding these ranges is essential for recognizing the clinical implications of elevated heart rates and managing patient care effectively.
