Preksha Meditation & Human Health: 4.8.1 Intra-Group Comparison Of RR Interval Variation (RRIV) For Experimental And Control Group Of Subjects (Table Nos. E 24 AND E 25) @ HereNow4U

At the onset of experiment, the mean value of RRI of control group of subjects was 0.87 ± 0.09 sec., which reduced insignificantly to 0.86 ±0.08 sec. after 90 days of experimental intervention. At the same time, the mean values of experimental group of subjects were increased to 0.92 ± 0.09 sec. at 90 days from its basal values of 0.89 ± 0.09 sec. Such change in experimental group of subjects was statistically significant (P d".0001) as shown in table E 23.

Table E 23: RRIV at 0 day and 90 days

Group	Duration	Mean (sec.)	SD	SE	'A'
Control (n=30)	0 day	0.87	0.09	0.01	0.13***
	90 days	0.86	0.08	0.01	0.13***
Experimental (n=30)	0 day	0.89	0.09	0.01	0.09**
	90 days	0.92	0.09	0.01	0.09**

Table E 24 and Table E 25 are showing a continuous significant increase in the mean values of RRI at 2^ndfollow-up phase (180 days) in comparison to the basal mean values in experimental group of subjects. A significant difference was also noticed in between 1^st follow-up and 2nd follow-up periods. However in control group of subjects no such significant changes were noticed at any follow-up stage.
