When the heart does not operate as it is supposed to and develops an abnormally slow heart rate that is less than 60 beats per minute, the condition is known as bradycardia.

What causes bradycardia while sleeping?

Transient sinus bradycardia: An increased tone in the vagus nerve, such as during sleep, often leads to this type of low heart rate. This nerve helps regulate the heart, lungs, and digestive tract. Once the vagal tone returns to normal, the heart rate also returns to normal.
