Cardiac problems occur as part of a wide range of signs and symptoms in ME/CFS. These include arrhythmia, bradycardia, chest pain, dysautonomia,[1]dyspnea, heart palpitations,[2]heart rate variability, hypotension, low blood volume,[3]neurally mediated hypotension,[1]orthostatic intolerance,[1]poor circulation (including cold hands and feet),[4]postural orthostatic tachycardia,[1]small heart syndrome,[5] small left ventricle,[6]Short QT interval,[7] reduced cardiac volumes[8] and tachycardia.

tachycardia An unusually rapid heart beat. Can be caused by exercise or illness. A symptom of postural orthostatic tachycardia syndrome (POTS). (Learn more:

myalgic encephalomyelitis (M.E.) - A disease often marked by neurological symptoms, but fatigue is sometimes a symptom as well. Some diagnostic criteria distinguish it from chronic fatigue syndrome, while other diagnostic criteria consider it to be a synonym for chronic fatigue syndrome. A defining characteristic of ME is post-exertional malaise (PEM), or post-exertional neuroimmune exhaustion (PENE), which is a notable exacerbation of symptoms brought on by small exertions. PEM can last for days or weeks. Symptoms can include cognitive impairments, muscle pain (myalgia), trouble remaining upright (orthostatic intolerance), sleep abnormalities, and gastro-intestinal impairments, among others. An estimated 25% of those suffering from ME are housebound or bedbound. The World Health Organization (WHO) classifies ME as a neurological disease.
