WebVarious studies have found that slow breathing increases amplitudes of blood pressure oscillations and HRV, and that this is particularly significant at a respiration rate of 6 breaths per min (0.1 Hz) [ 21, 61 – 64 ]. At 6 breaths per min, the LF HRV oscillations are said to be augmented by respiration [ 65, 66 ].
