Heart Rate Calculation Methods — ECG Academy Lesson

Turn grid math into a shift-ready rate decision: choose the right manual method for regular versus irregular rhythms and verify unstable digital readouts.

Learning Objectives

• Calculate heart rate using the 300 method for regular rhythms when a quick estimate is enough
• Calculate heart rate using the 1500 method when a regular rhythm needs a tighter manual number
• Calculate heart rate using the 6-second method when the rhythm is irregular and an average is safer
• Explain when the digital readout is reliable and when it must be verified manually
• Select the safest calculation method based on rhythm regularity and strip quality
