In brief: Sleep study

Many sleep problems increase your adrenergic tone and in response body will also increase parasympathetic tone and both of these can cause trouble with your heart rhythm. Also if there is a severe sleep abnormality or due to other medical conditions your oxygen drops during sleep that can affect the heart rhythm .
.... So heart monitor signal gives us this information.

In brief: Slower heart rate

Vagal tone (parasympathetic) is increased during sleep.
Does, heart rates are slower during sleep. In some sleep-related conditions, such as sleep apnea, potentially serious heart rhythms can be seen such as atrial fibrillation or profound bradycardia. Your dr. May choose to use a heart monitor to detect potential arrhythmias.
