If they are also sedentary, the risk is even greater, said lead researcher Paul Mork, of Norwegian University of Science and Technology in Trondheim, Norway. The study is published in the May issue of Arthritis  Care & Research . Fibromyalgia is marked by widespread pain lasting more than three months. The pain strikes so-called "tender points" in the neck, shoulders, back, hips, arms and legs.

The condition may be due to dysfunction in the nervous system and other problems, and it is thought to be affected by genetic susceptibility.

Most people experience transient rapid heartbeats, called sinus tachycardia, as a normal response to excitement,anxiety,stress , or exercise. If tachycardia occurs at rest or without a logical cause, however, it is considered abnormal. Description of Tachycardia The two main types of  tachycardia     are abnormal supraventricular tachycardias (which originate in the upper chambers of the heart, the atria) and ventricular tachycardias (which originate in the lower chambers of the heart, the ventricles). Causes and Risk Factors of Tachycardia Sinus tachycardias are most likely to occur in those who are easily excitable, suffer anxiety, or drink a lot of caffeine-containing beverages. They may also been seen in people with thyroid disease, with fevers, or with certain drugs (especial...
