Cardiac workload, more specifically known as myocardial workload, is a measure of stress put on the heart muscle. It refers to the amount of work performed by the heart in pumping blood through the body.

Cardiac Workload can be calculated using the formula: Heart Rate (bpm) x Systolic Blood Pressure(mmHg). This is shown in dB (decibels), measuring signal to noise ratio.

It is determined by the amount of blood pumped, the pressure at which it is pumped, and the heart rate. An increase in cardiac workload can be caused by physical activity, disease, or other factors and can have an impact on heart health.

Note: Our standard suggested range for Cardiac Workload is 0.00-4.28dB, however any figure >4.28dB can be considered Significantly Above Average and in the Very High Risk zone.
