Heart Abnormalities in Chronic Fatigue Syndrome


An Article in ‘About Health’.

By Adrienne Dellwo, Fibromyalgia & Chronic Fatigue Expert

Chronic fatigue syndrome (ME/CFS) is considered a multi-system illness with dysfunction in the immune system, central nervous system and hormones. However, research is suggesting that the abnormalities don’t stop there — ME/CFS is being tied to several irregularities in the heart.

These irregularities include:

  • Low nocturnal heart rate variability
  • Small left ventricle (in one subgroup)
  • Postural tachycardia
  • Short QT interval
  • Abnormal cardiac wall motion with exercise (in certain subgroups)
  • Low blood volume & reduced cardiac function

These irregularities may be to blame for some of the key symptoms of ME/CFS. They may also point to the importance of working to maintain heart health to lower the risk of cardiac problems.
