A member asked:

What are the consequences for decreased heart rate that varies with respiration?

A doctor has provided 1 answer

Probably nothing: Heart rate varies with respiration normally. It is usually not sensible however. A low heart rate may be a normal occurrence in a conditioned person, however if the low heart rate causes fatigue, dizziness or passing out episodes, it needs to be evaluated. Usually, a treadmill stress test is done to see if the heart rate responds appropriately, if not, the person may need a pacemaker.
