Key result
Cyclic meditation significantly increased the pNN30 statistic compared to supine rest (57.19 vs 53.27, P=0.024) in healthy women, indicating increased complexity in heart rate dynamics.

Cyclic meditation alters heart rate variability in women, specifically increasing sampling entropy compared to a resting state.
Cyclic meditation may enhance HRV complexity in healthy women; leaves open effects in clinical populations and long-term outcomes.
Certain time domain, frequency domain and a nonlinear measure of heart rate variability are studied in women following a meditative practice called cyclic meditation. The nonlinear measure studied is the sampling entropy. We show that there is an increase in the sampling entropy in the meditative group as compared to the control group. The time domain measure called pNNx is shown to be useful in distinguishing between the meditative state and a normal resting state.

Kulkarni et al. (2010) studied Healthy (n=28). Cyclic meditation vs. Supine rest was evaluated on pNN30 statistic (p=0.024). Cyclic meditation significantly increased the pNN30 statistic compared to supine rest (57.19 vs 53.27, P=0.024) in healthy women, indicating increased complexity in heart rate dynamics.
