The before ECG shows a higher heart rate and a lower heart rate variability.  This is is indicative of a sympathetic (stress response).  This activity will actually cause more stress and not lead to improved health or well being.

The after ECG shows a lower heart rate and a higher heart rate variably.  This is indicative of a disarmed nervous system that allows stress to be taken away leading to improved health and well being.
