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


What is the significance of the Cardiac Cycle Time in medical diagnostics?

Cardiac Cycle Time (CCT) is crucial in assessing the efficiency of the heart’s pumping action. Shorter or longer CCT can indicate various cardiac conditions, helping physicians diagnose and manage heart-related issues effectively.

Can the Cardiac Cycle Time vary from person to person?

Yes, CCT can vary among individuals based on factors such as age, fitness level, and the presence of cardiac conditions. Athletes, for example, often have a lower heart rate and longer CCT, indicating a highly efficient heart function.

How does an abnormal Cardiac Cycle Time affect the body?

An abnormal CCT can lead to insufficient blood flow to the body’s organs, affecting their function. It can manifest as fatigue, dizziness, or more severe symptoms, depending on the extent of deviation from normal values.

Are there any lifestyle changes or treatments that can improve Cardiac Cycle Time?

Improving cardiovascular health through regular exercise, a healthy diet, and avoiding harmful habits like smoking can positively influence CCT. In some cases, medication or surgical interventions may be necessary to correct underlying issues affecting cardiac function.
