How to treat palpitating heart?
Patient: have woken up around 5am a few times with my heart racing like I have been running/aerobics in my sleep. I do not remember dreaming of running. My breath is not labored. when I notice my heart is racing it comes back down, quickly just as it would while cooling down from an Aerobic workout. 30 years teaching fitness, aerobics, and yoga. Doctor: Hi. Thank you for your question. Heart racing during sleep is a known phenomenon. It happens during the REM (rapid eye movements) phase of sleep, a phase characterized by a flush of catecholamines (e.g. adrenalin) in the system, which causes heart rate to "race". I am assuming it is a regular beat. My opinion is that no further investigation is warranted. I hope I was helpful. Greetings.
