Tachycardia/ sleep: How fast?? There is always variation in rate . When we sleep there is more autonomic tone effects with increase in sympathetic tone in REM sleep. Most are benign but may consider EKG or holter, echo including mitral valve prolapse ) and check for sleep apnea. Caffeine, alcohol,anxiety also promote tachycardias. f/u w/doc
