The emWave2 is an advanced heart rate monitor, able to measure subtle changes in your heart rhythms. This type of measurement is known as heart rate variability analysis or HRV. The analysis of HRV is a noninvasive measurement that reflects heart-brain interaction and autonomic nervous system dynamics, which are particularly sensitive to changes in your emotional state.
