What Are the Causes of Heart Palpitations & Twitching During Sleep?
According to a 2007 review in the “Journal of Clinical Sleep Medicine,” sleep occurs in a progressive series of stages. People typically experience light sleep, deep sleep and then rapid eye movement sleep. This last stage is also known as REM sleep, and it’s associated with dreams. During REM sleep, the body is paralyzed, yet the mind remains active. Heart palpitations, body twitches and eye movements are often observed. While these events are normal, they can be excessive or occur in other sleep stages. Such outbursts may be symptoms of an underlying medical condition.
