Heart Abnormalities in Chronic Fatigue Syndrome

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.
