Enter the total heart rate (BPM) into the Calculator. The calculator will evaluate the Cardiac Cycle Time. 

Cardiac Cycle Time Formula

CCT = 1 / HR


  • CCT is the Cardiac Cycle Time (minutes per beat)
  • HR is the total heart rate (BPM)

To calculate Cardiac Cycle Time, simply divide 1 by the heart rate in beats per minute.

How to Calculate Cardiac Cycle Time?

The following steps outline how to calculate the Cardiac Cycle Time.

  1. First, determine the total heart rate (BPM). 
  2. Next, gather the formula from above = CCT = 1 / HR.
  3. Finally, calculate the Cardiac Cycle Time.
  4. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total heart rate (BPM) = 60
