Key result
Meditation is linked to increased HRV complexity and altered heartbeat correlation versus baseline.
Why the study?
The effects of meditation on the scaling behavior and complexity of heart rate variability in individuals with a normal heart were not well characterized.
Does meditation affect the scaling behavior and complexity of heart rate variability in individuals with a normal heart?

Does meditation affect the scaling behavior and complexity of heart rate variability in individuals with a normal heart?
Meditation alters heart rate variability by inducing periodic behavior and increasing signal complexity in normal hearts.
Meditation HRV changes should not alter practice; hypothesis-generating for fractal scaling in autonomic research.
The heart beat data recorded from samples before and during meditation are analyzed using two different scaling analysis methods. These analyses revealed that meditation severely affects the long range correlation of heart beat of a normal heart. Moreover, it is found that meditation induces periodic behavior in the heart beat. The complexity of the heart rate variability is quantified using multiscale entropy analysis and recurrence analysis. The heart beat during meditation is found to be more complex.

Sarkar et al. (2008) conducted an observational in Normal heart. Meditation vs. Before meditation was evaluated on Scaling behavior and complexity of heart rate variability. Meditation severely affected the long-range correlation of the heartbeat, induced periodic behavior, and increased the complexity of heart rate variability compared to baseline.
