The named ranges used to describe where a setting's pulse rate falls: Delta (0.5 to 4 Hz), Theta (4 to 8 Hz), Alpha (8 to 12 Hz), Beta (12 to 30 Hz), and Gamma (above about 30 Hz). The names are borrowed from EEG brain-wave naming and label the pulse rate only; by themselves they do not indicate a specific effect in the body.
Also known as: Delta Frequency Band, Theta Frequency Band, Alpha Frequency Band, Beta Frequency Band, Gamma Frequency Band
The band names are borrowed from EEG and mark where a setting's pulse rate sits on the frequency axis: Delta is the slowest, Gamma the fastest. They are labels for the pulse rate, not a promise of a particular effect in the body.
