REM sleep-related sinus arrest (RSSA) refers to a medical condition characterized by the temporary cessation or pause in the electrical activity of the heart (also known as sinus arrest) specifically occurring during the rapid eye movement (REM) phase of sleep. REM sleep is a stage of sleep characterized by intense brain activity and rapid eye movement, during which most vivid dreams occur. Sinus arrest refers to the halting of the normal electrical impulses that regulate heart rhythm, leading to a temporary pause in heartbeats.
During RSSA, the sinus arrest episodes are predominantly observed during REM sleep, although they can also occur during other sleep stages. The exact cause of REM sleep-related sinus arrest is currently unknown, but it is believed to be associated with an abnormality in the autonomic nervous system, which controls the involuntary functions of the body.
Symptoms of RSSA may vary but can include nocturnal syncope (fainting during sleep), witnessed apnea (temporary cessation of breathing), and palpitations. The duration of the sinus arrest episodes can range from a few seconds to several minutes, and the pauses in heart rhythm usually resolve spontaneously. However, severe cases may require medical intervention.
Diagnosis of REM sleep-related sinus arrest involves monitoring the individual's sleep using polysomnography, a test that measures brain waves, muscle activity, breathing patterns, and heart rhythm during sleep. Treatment options for RSSA include the use of medications that regulate heart rhythm, such as beta-blockers or pacemaker implantation, depending on the severity of the condition and the associated symptoms. People with REM sleep-related sinus arrest often require regular follow-up with a cardiologist and sleep specialist to manage their condition effectively.
