Pacing with a heart rate monitor

A person's heart rate increases with their physical activity level, and decreases when they rest. Heart rate monitors offer a simple and accessible way to monitor activity level in order to help ME/CFS patients avoid the over-exertion that causes significantly worsening symptoms. Heart rate monitors typically display the person's heart rate on a monitor that is worn like a wristwatch, and many have audible alarms to alert the person if their heart rate rises above (or below) a value they have chosen.

Theory
People with ME/CFS have mitochondria dysfunction and biological abnormalities resulting from the disease which significantly restrict the amount of energy they can use for everyday activities. Doing activities that exceed available energy usually triggers a flood of cytokines causing pain and immune symptoms, and a variety of other negative affects also occur, resulting in post exertional malaise (PEM).

Some researchers believe that each time PEM is triggered, it is reactivating the disease process of ME.

Using a heart rate monitor, to measure heart rate, heart rate variability, and other factors, allows people with ME to observe their energy usage, and learn how to stay within their safe energy limits.

This pacing method is often used in conjunction with other treatments (electrolyte loading, pharmaceuticals to assist blood volume & cardiovascular function, extreme resting and meditation, etc).

Evidence
Anecdotally, some people experience gradual improvements in their health, with occasional setbacks due to over-exertion, infections & immune reactivity.
