INTRODUCTION:
There are so many methods to calculate hart rate , common methods are listed below:

– Rate Calculator
– Rate Calculator
6-Second Interval x 10 Method
• Quick and easy and does not require tools or devices
• Not as accurate as other methods
• Multiply the number of QRS complexes found in a ten second portion of ECG tracing by 6.
RULE OF 300 :
When the cardiac rhythm is regular, the heart rate can be determined by the interval between two successive QRS complexes. On standard paper with the most common tracing settings, the heart rate is calculated by dividing the number of large boxes (5 mm or 0.2 seconds) between two successive QRS complexes into 300.
RULE OF 1500
To use the 1500 method count the number of small squares between two consecutive R waves and divide 1500 by that number.
• Cannot be used with irregular rhythms.
Rate Calculators
• Easy to use but not always available
• Ineffective on irregular rhythms where a consistent baseline is not present
• Position the “start mark” on an R wave
• Then find the next consecutive R wave – where it lines up is the approximate heart rate
