Cardiovascular problems in ME/CFS

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