ECG Heart Rate Calculator: Accurate EKG Rate Calculation Tool

Calculate Heart Rate from Your ECG Strip

Enter the number of small squares (1mm) between two consecutive R-waves.

Our free online ECG Heart Rate Calculator helps medical students, nurses, and healthcare professionals quickly determine heart rate from EKG strips. Utilize the 1500 method, 300 method, or 6-second method for accurate results. Simplify your cardiac rhythm interpretation and enhance diagnostic efficiency with this essential, user-friendly tool.

Formula:

This calculator uses three common methods to determine heart rate from an ECG strip:

  • 1500 Method: Best for regular rhythms. Heart Rate (bpm) = 1500 / (number of small squares between two consecutive R-waves)
  • 300 Method: Also for regular rhythms. Heart Rate (bpm) = 300 / (number of large squares between two consecutive R-waves)
  • 6-Second Method: Ideal for irregular rhythms. Heart Rate (bpm) = (number of QRS complexes in a 6-second strip) × 10
