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
